I really wish that there was a way to not see everyone's stupid macros.
I don't care that you're summoning garuda, nor do I need to be reminded every 2 minutes that she's the goddess of wind.
Likewise I don't care that you're casting Utsusemi. Unless for some reason you're riding the ichi timer and haven't learned to cast it without it being interrupted so you need it to be stunned.
The worst, of course, are the ones in /say or /emote, and the new /jobemote only seemed to encourage this. Though at least you can /blacklist these guys if they're not in your pt.
