I dunno just my PoV. Honestly the way I imagine doing that much more damage at the end is if I had rediculous uptime on my target. Recently I've done arenas against Nazgrot and that dude knows how to keep my partner next to him and me at the other side of the pillar. His only downfall was that when he does that I simply switch to this dpriest which is probably my favourite healer to hit. At the end our damage ended up somewhere even.
Maybe you're right, maybe not. Maybe I'm dillusional, maybe I've actually learned a thing or two :D .
p.s. No hard feelings I ain't playing games to make enemies.
