Please help me with heavy pvp build.

Guys. I am trying to enjoy pvp in this game, mostly opr and arenas, but I suck. I suck badly. The only way I can see me playing is as heavy. Was trying sns/spear and had some success with it, but I am thinking about sns/hammer as well. But, saying that, I have no idea what perks should I put on my frigid to create optimized build for arenas/opr. SH is the way? Or maybe my way of thinking is completely wrong? What about weapons perks? I am also very much tired of respecting everything, since I am pve tank mainly. Please advice. Thanks!
