Truth be told, I didn't feel like it was simplified too much at all nor do I think many jobs have been dumbed down. Sure, the bottom is raised and doing basic DPS is easier these days, but I'm really sure (especially looking at SAM's possibilities) we'll be fine.
Anyway, we'll cross that bridge when we get there no? Let's not panic based on the things we've seen so far and reserve final judgement until we actually get to play it. Panicking like your life depends on it isn't a good thing to do about a videogame anyway. :)
