Macro's that are actually useful ?

[Paladinleeds]

Every tank should use this countdown macro instead of that garbage ready check.

Do you know that when ready check window pops up on the screen while people are preparing for their attack opener, it's VERY VERY VERY ANNOYING!! Stop doing it. Just use a countdown macro so everybody can time their opener properly.

I hate countdown macros. Overly annoying.
Any in-battle macros are also going to impede your flow over time as they can't queue like an ability can. Even if it's just to announce you've done something. I can't tell you how often a Provoke macro never actually used Provoke, ending in a very dead other tank.

As someone else mentioned, crafting macros tend to be the only useful ones. Perhaps lengthy explanations or gear lot rules perhaps. But not for anything in battle itself.

Actually, I have some macros. All abilities tied to it are oGCD if they involve abilities (with the exception of the provoke macro which also fires Shield Lob/Tomahawk/Unmend a second later if I fail to react after the provoke, but I am getting better at manually handling the bit after the provoke). I use a provoke macro, a SwiftRess macro (no hard ress one), one for my Hallowed Ground (Holmgang and Living Dead are NOT macro'd), and a pull macro. I also make macros to announce certain mechanics and how to deal with them, or manage positionals, etc. They're the ones that announce stuff to players that I actively use.

I also have 2 macros that don't announce stuff. These are Defiance and Deliverance. What these do is they /echo what ability got used, and adjust my hotbars so that abilities I can't use get hidden for abilities I can use. When I use the Defiance macro it adds Inner Beast and Steel Tempest to my hotbars, and vice-versa for Deliverance, which adds Fell Cleave and Decimate to my hotbars. When they're used, they replace the abilities found in the other.

Crafting macros? I don't use them. I manually click every single ability (which I don't mind doing, since I have a 17 button mouse)
