I think one of the big reasons for the uproar about this too is (I'm sure someone else said it but I haven't read much of the thread) is that, with so very very few BG2 type RPG's to even come out now, losing one is a real kick in the nuts. In the past, if one failed or or went in a totally different direction there was a dozen more to take its spot so it wasn't issue.
Personally I am not happy, I love oldschool RPGs and not these new action games with some dialog and stats thrown in now. While they are fun they aren't the same experience at all. That is fine for those who love the new ones. Those of you saying you are glad it is simplified don't have as much time to play a long drawn out deep RPG, my question is why do we need to change one of the few out there to cater to what you want while there are plenty that fit you bill perfectly already.
Those of us that like the older style have nearly no options so we get pissed when we lose what little we have. If you weren't interested in these type of games before due to the complexity/time/whatever it takes to get into them, no one was forcing you to get it, you could of just gotten another game that has similar qualities that fits your needs as the selection is much more plentiful for you.
This is like taking Starcraft and making it into Company of Heroes. Sure both, RTS, but totally different.
