I don't see a problem with teleportation spells since some people with like 6 speed or speedhacks just run across the whole map in 10 seconds anyway
And yeah, most things really should have been class-specific from the start, such as magic for mages, praying for priests, bows for barbs and uh, whatever the heck for the other classes XD
Pity it's too late now, the only time to make things class specific would probably be at the reset
