But don't you think it's in their self interest to make the game enjoyable long term?
No idea where you inferred that as I didn't say it. Who's to say they will "fix" it how people want though? Their design ideas seemed to differ quite a bit already from previous iterations and despite that conflict they pressed ahead.
Sure I'm hopeful that they revisit the loot tables but I don't take it for granted as they seem to have a lot of concern with how things balance and whatnot, as if this was an MMO title or something. Cautiously optimistic I guess. To be fair though D2 wasn't perfect and the expansion fixed a lot of the problems.
