Slow down there Blizzard... lol
I can understand some people's complaints and like to participate in ideas or trying to be constructive to the criticism, but at least given the game has done better and better .. not sure it's on the death bed like some people type. BUT I am of the belief you should be careful not to wait till your deathbed to do something about the concerns people have lol, so if there is a growing mass.. if it's possible.. try to pop it before it's a painful mass
I don't fully agree with everything in the OP, or think some are as bad as stated, but as I said I do think some points are interesting or SE should be mindful (like what I've said in the healer centric thread). Each point would require it's own response so I'm not going to give a general "this is what I think might be good solutions" because it would change drastically on each point, and theoretically they could do nothing as you said and at least for a 'while' they'd be fine xD.
Besides I always like the hungry position of a company over "we're settled and you can expect nothing more from us but less" lol. I like when they try new things, even if I don't like those new things.... ... and I feel they do, sometimes slowly, adjust those things from feedback- so that's nice too.
