Need help with stone/fire brawler build

so far I have
Stonefist
Stone mallet
Heavy mallet
Fire Shield
Blazing aura

Im level 8 and don't know what to do


I want to do mostly PvP and 2 person missions, thats what I'm doing so far at least

I don't know terms well, but I've been playing a while, just need some real advice


Thanks

I would recommend going to the archetype & powers section of the forum, there are alot of build suggestions over there. when I start a new toon I'll look at those for ideas, but everyone plays different and some of the max builds can get expensive. I don't have a stone/fire so I cant give any specific help.
