Hi there, I consider myself a fairly hardcore player. I lose ABSOLUTELY NOTHING from this buff because, hey, holy shit, if a casual player, or hell, even a BAD player (my god, there's a difference!) gets gear, guess what, it doesn't matter, because I'm not raiding with them anyways!
Imagine that. OP, stop giving a crap about what people you don't raid with are able to do, for some casual guilds, the huge buff means that they may finally have a chance to kill LK or something. The buff still isn't going to allow casual guilds to faceroll their way to HC LK, or even 11/12 HC, if that far. If you're a hardcore player, then you already killed him a long time ago anyways.
Edit: upon rereading the OP's post, I can't actually figure out what he is crying about, exactly.
