I have seen a few Wizards built with a lvl of Sorc and am wondering the reason. The only 2 things I can think of are:

1: Maybe (I dont think so but maybe) they get double SP from their items.
2: Maybe (I dont think so but maybe) all of their Wiz spells are now cast as fast as a Sorc would cast, and their timers now recharge faster too.

Are these the reasons or am I missing something?
