Im not sure that it would be overwhelming, BUT I'd rather that than what they're doing to actions and abilities. (and in turn, the balance and strengths of each class) I don't mind them starting at level 1 - as a D&d fan, I'm good with it. But if they're worried about martial classes having things to do - I think level 5 is a better solution. otherwise, level one eases everyone into everything - less actions and all.
