no dude.....wizards do not get much better at all until Luclin when you start getting mana regen AAs and FT is more available.
at lvl 50, you can do a few things.....
I suggest Giant Fort in BW, BW in general.....at lvl 54, you can start quadding effectively....but ya....wizards are pretty over rated.
O ya, you can actually kite ice giants easily....
