Yeah, that's exactly how it was described. Keeping the same animations but only playing every third frame is a nice touch.
People who say that Diablo 3 was watered down and that the first two were much better games probably haven't played them recently. I only played D2, but the stamina bar, constant restocking of potions on your belt, only having two abilities active at one time, inability to experiment with builds without starting an entirely new character, lack of difficulty options (that, granted, Diablo 3 didn't have until RoS), all of these things made D2 a much more irritating experience. Diablo 3 is an excellent game, full of Blizzard's usual charm and polish. I'd rather we got an entirely new expansion than just the Necromancer character pack, but I imagine it'll tide me over.
