I don't know if anyone else is already using this I thought of this myself, but I'm running a Nord Stamden with Werewolf hide and Mech Acutity medium armor with heavy shoulders and helm (Currently engine guardian to be replaced with Balorgh when I get it) I can spam my low cost ult and use permafrost quite often, especially when people are shooting projectiles at me (shimmering shield). I use ice fortress, draining shot, poison injection/venom arrow cliff racer and sub assault as well. 2h/Bow Setup I also got the 2h executioner skill.
Mech Acutity is to offset low weapon crit, WW hide is to further boost ult gen, Balorghs will grant me a huge weapon damage boost whenever I use an ultimate (I think it also gets bigger the more the ult costs).
So far even without balorghs its performed far far better than any of my previous characters in PVP. I look forward to getting better at using my build and maybe finding ways to improve it.
Playing your character the way your character should play is all that matters. Play as well as you can but never betray the character. Doing so would make playing an mmoRPG pointless.
