Whether you're right or not, you need to be a little less insulting in providing your refutation. Hint: direct your critiques at the argument and not the poster. Thanks.
So exactly how do you propose Blizzard design aoe damage so we still have a role aoe healing? A mild tickle in 6 second intervals?
Have you lost your perspective? 12,000 heal, instant cast, spread out across 6 raid members is the highest output (*) spell in the game. These are level 80 numbers from Naxx. How can anyone take your seriously when you describe 12,000 as a mild tickle?
(*) Prayer of Healing can actually do better under perfect conditions.
