I was wondering if there is a way to first check if my trinkets are off cooldown and THEN use /use them.
Here is what the problem is.
My macros look BASICALLY something like this.
Problem with this method is when my trinkets are on Cooldown I get bombarded withItem is Not Ready YetandSpell Is Not Ready Yeterror messages, which significantly reduce my casting speed, which is a BIG problem in PVP. You know every failed spell or trinket use trigger a GCD of like 0.5 or more.
I need some way to check if the trinkets are ready before executing the /use command and if they are still on Cooldown, the macro should skip the /use 13, 14 part and proceed directly with the spell-cast.
Here is how I imagine it, USING PSEUDO-CODE to just represent my idea.

Anyone got any idea how to resolve this ? I used the Search function but didn't find anything relevant to my problem.

The macro in the comment works because he has a shift modifier when he wants to equip the trinket. So he would hit, for example, shift-KEY to equip the dragonling, then he would just hit KEY to use the dragonling then equip his other trinket. This would have to be done out of combat to work. To break down the previous macro into a readable psuedo-code: Equip TrinketName in slot 14 End Macro Else if right-clicked Equip TrinketName in slot 13 End Macro It never even gets to the 'or if right-clicked'- it just reads the first command and then ends the macro. By swapping it around, you get: If right-clicked Equip TrinketName in slot 13. Use equipment slot (for engi gadgets, trinkets, offhands, etc) #showtooltip /use number. Uses the item in the slot number number. 1 = helm, 6 = belt, 8 = boots, 17 = offhand, 13 = trinket1, 14 = trinket2. Feel free to add mouseover conditions and such to this! Pet-specific binds, with modifier set. /equip trinket 1513 - this will put the trinket that you type the name of into slot 15, which is your first trinket slot. Your second trinket slot is 16 14. You could also just use gear sets from your character screen. Edit: I was incorrect on the trinket slot numbers. Here's a full lazyman's trinket macro that I use on my Death Knight. It rotates between three tanking trinkets on my top trinket slot, and uses that top trinket slot on normal click.

Warlocks are a class of far too many key bindings and niche spells for niche situations. Having a solid knowledge of macros will help you intelligently combine multiple actions to a single key, increase your responsiveness to emergent situations, and, to an extent, automate tedious tasks.

My goal with this document is not only to list out what I have found to be the most commonly employed warlock macros, but to give you enough information so that you can begin to modify and even write your own macros going forward. For this reason, I strongly encourage you not to simply copy and paste these macros, and instead hope that you try to understand what the syntax means.

Macro Basics

The macro editing window can be brought up by typing /m in the chat window. There you can write, edit, and store macros either for your entire account (if the macro is useful for multiple characters) or for just the current character (if you have a class-specific macro, for example).

Create a new macro by clicking “New”. Then you will have to give the macro a name and an icon. Personally, I don’t like text appearing over my skill icons so I tend to name my macros “ “ which is just a press of the spacebar. For the icon I typically suggest using the first icon, the red “?”. This icon is special, because it will adapt to the functionality of the macro. It will automatically attempt to find the appropriate icon based on the action performed by the macro.

First Macros

After you’ve chosen a name and icon for the macro, you must write the functionality of the macro – what will the macro do? In the big box at the bottom of the macro editor window (where it says “Enter Macro Commands”) you can type something as simple as:

/s Hi

Then, if you drag the icon for this macro to an action bar, and press/click it, your character should say “Hi”.

Now try something more useful. Create a macro that has the following command:

/cast Demon Armor

Now you’ve written a macro that will cast the warlock spell Demon Armor for you! You might not think this is very useful, since you could have just had the spell on your action bar in place of the macro. You’d be correct, but this macro’s functionality is more subtle and useful than you think. This macro will automatically use the highest rank of the spell! As you level, you will never need to replace Demon Armor with the new rank; just use this macro and you will automatically have the highest-rank spell available.

A More Useful Macro

Macros are only useful if they save you time, key presses, or action bar slots. Getting the most out of a macro means having a basic knowledge of what a macro can do. Here’s an example:

/cast [@player] Devour Magic

This macro will use the Felhunter’s Devour Magic spell (assuming he is the active summoned demon) on you, even if you have an enemy targeted.

Notice the “@player” inside the square brackets. This is called a conditional and it modifies the nature of the action being performed.

Actions

Most macros are meant to use and/or equip items, cast spells, announce your actions to appropriate chat channels. Here are some of the basic actions a macro can perform:

/cast Cast a spell. Probably going to be your most-used type of macro command.

/stopcasting Interrupts a spellcast. Useful in front of /cast or /use commands, to interrupt your cast and complete your next action faster.

/castsequence Cast several spells in a pre-determined order. You can have the sequence reset upon special circumstances.

/use Use an item, such as health/soul/spellstones, potions, food/water, trinkets, whatever.

/equip Equip an item from your bag. Will induce a 30-second cooldown on items with a Use effect.

/say Self-explanatory

/party Self-explanatory

/raid Self-explanatory

/r Responds to a whisper. Can make a macro that says “Leave me alone I’m watching Asmongold!”

/dismount Takes you off your mount. This is handy to put in front of a /cast macro for your opener spells.

/userandom Uses a random item from a list you specify. The only use I can think for this is to summon a random non-combat pet 😛

/petaggressive Set your demon to aggressive.

/petattack Command your demon to attack.

/petautocasttoggle One button to turn on/off autocast for a specific demon ability.

/petautocaston Turns autocast on for a specific demon ability.

/petautocastoff Turns autocast off for a specific demon ability.

/petfollow Recalls your pet to follow you.

/petpassive Set your pet to aggressive.

/petstay Command your pet to stay in place.

/targetlasttarget Targets your previous target, without having to find their name/unitframe/nameplate/character.

Conditionals

Here is the focus of the guide portion of this document. If you can understand this, you’ll be able to write useful macros for any situation, on any class (though of course you only play Warlock, right?).

You can chain these together to make very nice macros. Mix and match them to suit your needs.

Here are some of the most important conditionals, with a brief description of what they do:

Targeting

Target tags can be chained together as well. For example, @targettargetpettarget will cast at your target’s target’s pet’s target.

@player Casts the spell towards the player (you) regardless of what you have targeted. Good example being the previously shown Self-Devour macro.
@pet Casts the spell towards your pet regardless of what you have targeted.
@targetpet Casts the spell towards
