Hello XD (First post)

I know many RPG games utilizes classes, and many RPGs use builds, or a more familiar term, Specializations. Such as, if I want to be a mage, could you specialize in Fire? I know there has not been too much information on this game, but I was wondering if I missed something and someone on here knows the answer.

from what I gathered at e3 it seems like you do get to choose your playstyle. There is loot that mimics magic. For example there's fireworks like bottle rockets or ("moon candles"?) that mimic magic missile. Magic isn't like burning hands in D&D, rather it's Cartman lighting his farts on fire.
