whats the best magic to be proficient in for mages?

It's personal preference man. Depends on whether you want your damage more focused or more wild.

It's totally personal. I like consistency so I use Earth and Focused Heal, but some people absolutely love Lightning and Wild Heal

what about fire, ive been usin that for like the first couple of lvls

If I remember correctly, fire is in the middle, its not wild, but its not the most focused either.

I would suggest trying them all and seeing what you like. You wont really notice profiencies until they have a few levels on them, so you have the luxury of testing them all, especially at low levels.

thx for your help guys, i've been working with earth and i love the consitency. i think i'll stick with that.
