Frost and Arcane are the closest brothers gear wise (haste/mastery), Fire requires a completely different gear set (crit) as above
Playability they are good fun but require graphical/mechanic updates to feel less clunky and to look and feel more epic.
Frost point of view is awesome for control and dominance over enemies. (but cant cast whilst moving outside of procs)
Fire moveability whilst casting and ZOMG pyro balls.
Arcane for massive crits (but poor ramp up time and static HOW DARE YOU MOVE dps)
