i am currently trying out 1h warrior/warlock pure str. its lvl 23 now.
it does good in PvE. i kill party giants quite fast and i zerk a lot(every 2-3 mins or so). i just use the curses first then switch back to 1h sword.
as for PvP, it annoys a lot of people when i just do daze+vampire+slumber rinse and repeat ad infinitum. i cant kill them yet so i pester them.
i am still unsure how it will do later at higher lvl. i think impotent/division will make my low-damager 1h warrior go suddenly very deadly pvp-wise. stun+lock first to pile curses and debuffs on the target then switch to 1h sword FTW
