I am currently Wiz>Pyro>Linker>Ele and I can say you are pretty decent with AoE magic. Though having only one rank of each, you cant take advantage of the good attribute the class have seeing most of them are on circle two. I hardly use the Ele skills seeing they have a long cooldown and I am stuck using pyro skills in general. Linkers are handy during boss fights as you can clear traps easily by binding the boss with it.
I would suggest go with Wiz>Pyro>Linker>Pyro2>Pyro 3. Pyro has Flame ground which is better than most Ele skills though it can’t hit flying enemies (which you would link a ground enemy with a flying one to hit it)
Build two is decent as well if you take advantage of Ele attribute that explodes enemies if finished off with a fire attacks (making linker some what irrelevant)
