Berseker guides?

I would like to know best pve build and then best pvp build if it is possible...i m planning to lvl up to like 60-70 lvl with pve build and then reset and change to pvp atm 20 lvl with no skills -.-.... trying to find some build - i think i found out all classes but not berseker last hope here or i m changing character

better to ask at official forums
but anyway zerks are easy to play and build so not that hard to get 70+
