Being asked to stop spamming Holy amongst a group of mobs in a dungeon sure was something. I firmly said no and suggested that if it bothers them, they could turn party battle effects off. I could have gone a step further and said they could use their AoE's as well (I was the only person using AoE's. SAM and BLM did not AoE), but I had a hunch they queued as a group of friends... though thinking about it, getting kicked would have saved me so much time.
Then I got Pharos Sirius normal in Level 50/60/70 Roulette and everyone ignored the adds. So that was extra nice.
Wanna know what happens when all the eggs are destroyed in the first 10-20 seconds in the Zu fight? A very frustrated healer.
