well, since hunters are gonna get focus and shamans are supposed to get spirit, i wonder how majorly fucked up shaman itemization will be... enhas either no longer sharing all loot with hunters = more QQ about 1 spec items OR they will share same items, but will be way weaker, unless blizzard also reworks completely how enha works. ans ele and resto with spirit? well it might help eles o get some decent gear without waiting for 3 drops in whole instance, but i already see lots of clothies QQing about "shamen stole my gearz!!11" And it didnt solve holy pala "gear for only one spec" question at all, paladins will want cloths, too, since now those will be worth it even more, yet they will have their unique gear noone can take fom them.
talent tree bonuses pretty cool (tho it might discourage hybrid dps to specc few points in off trees, if bonuses from main one will be superior to those minor talents from off trees...), phasing pretty cool, warlocks no longer needing loads of shards cool, overall meh.
