Maybe its realistic, but model don't change at higher lvl's, looks same as low lvl. Mamy skin can be more detailed, but nothing more...

At movie, we see that sorcerer have book whit a glowing symbol, thats all. Staff will also look good whit sorcerer.
Anyway its a beta, they will add more weapons like books or staffs.

Itsa a bug when u throw a spell yours weapon disappear? Do they fix it? Its realy stupid wearing a weapon that you can't use in battle! ...
