So true. Most people in raid settings would be too busy doing other things than watching the numbers/text popping up above their heads showing what happened to them. They would be focusing more on fire, timers (boss abilities + their own cds/dots), positioning etc. I know I hardly ever look at my toon so animations on my toon is largely ignored by me.
Also we're talking about a PVE setting, not PVP where a lot more people will notice every scrolling text + animations on toons. More important in PVP than PVE imo since you need to watch what your opponent is doing and what colour/stance/shit glowing above his head in order to counter them.
Spam casting Light of Dawn with the DM healer trinket or Ai-Li's Skymirror will still be the ultimate holy pally troll mechanism. Thats what needs to be fixed, not our 4 piece.
