Learning from their mistakes? They did it correctly the first time, but I guess because of lack of time/budget they failed to do so properly with D2, or just forgot about it. Anyway, hopefully in D3 there won't be a situation like that. Losing valuable health points with getting nothing for it is not something I enjoyed, especially since I play on nightmare (...I only switched the difficulty down when fighting Zagaz, that demon from the High Hall)
