PVE thief
Zerker is where you want to be eventually but it might hurt until you get some experience. A compromise might be to use some defensive trait lines such as shadow arts and acrobatics. You can use any sensible build and weapons really so that’s why nothing is 100%.
Thieves are mid range for dungeons and fractals. Most groups want heavy armor classes but won’t turn a thief away (but may turn away a second).
