My Provoke has no /p line, as I am pretty sure people can tell that I just provoked by the big orb that is made and the monster is now facing me. I do use a /echo Provoke in 15 and /echo Provoke ready.
When I use Ninja debuffs I use simple, Using (Hyoton) ice damgae lowered. Debuffs like blind, slow, and paralyze I do not announe, as the chat window will say if the mob gets that effect.
I don't have an say for steal, no reason that anyone needs to know. Sneak Attack I announce and give 3 second timer, since it is very important that people know, "Using Sneak in 3 seconds".
All the RP macros or nonsense to me, I often open chat while fighting cause I thought someone actualy said something useful, but no, it's just an annoying little, "I will bring thee to thine knees, JUMP!". I'm sorry but all that stuff is just way to annoying to me, but I can't rain on someone's parade for it, just wish I could filter that kind of party chat ^^. Maybe I should make one that says "Go Go Gadget STFU macros that are annoying!"
