What's the point of these threads? Most people aren't saying they aren't good enough or that they don't know what to do - they're saying they dislike the new healing model. Please notice the difference between the two. I'm perfectly capable of adapting to the new model and successfully healing. I just think it's a bad, unenjoyable model.
This is exactly how I feel. There is more going on than "lololol casual baddies gtfo my game go play hello kitty island noob!!1!"
I can tell there are people who are delighted and want to see the population of healers dwindle until we're left with just the most hardcore. It's a strange kind of revenge for these people, I think. Wrath ruined their game, and now, payback is hell. But in the end, if healers stop queuing in LFD, and we're left with a handful of hardcore pockets of guilded healers who don't pug ... the game suffers. It's the opposite extreme of the Wrath model where everybody is a winner and everyone gets a prize.
But this new healing model, where you weaken as you level, and costs rise sharply but give rapidly diminishing returns ... that's just depressing. I mean, I rather enjoy watching my toons get more powerful, not more crippled.
I shudder to think what pvp healing will be like now. But I guess that's another issue.
