So I had this strange thought: using sorcerous blade channelling, I can use ranged attacks at melee range without fear of retaliation, and dragon shaman has more than a few blasts that would be useful, as well as a crapton of powers that hurt people that hit you.

I understand that it's not very optimised (also heard that sorcerer is a weak class but that is neither here nor there), but can a melee/point-blank range sorcerer be done, and if so, how should it be done?, and what other feats should I have?
