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)
