No way I am goping to get involved in a critical analysis of 3E now, amigo. I will say that while you suggest that some players stick with a single-class character, is that because of the way the game is done or in spite of it? Also, the way that skills and feats are presented tends to both encourage multi-classing while blurring the archetypes. Yes, one can still play 3E with archetypes, but the system does not encourage it, nor is that in the spirit of the system--gaining power.
That's all from me on this topic.
