I think there needs to be some changes to the loot stat randomizer. Some abilities seem rather overrated. I have all these legendary and epic gear with some of the most useless stats such as +45 hp + 5 str, crappy life leech, crappy mana leech on a two handed sword. Well great...i end up disenchanting the life/mana leech anyway. And often I get legendary or heroic stuff that are way better. Such as a heroic pendant with a level 10 static charge and +1 the summon demon which i found at level 17...damn that demon is an awesome tank. Heck some of the uniques get rolled with pretty crap stats too.
Might also look towards reducing the number of item rarity classes. All these names get confusing.
