Third class conundrum

So I’m currently running SL/CLR/BER. But I’m feeling like berserker isn’t doing much for me aside from the stance, i like that the paige line of spells and vampiric embrace kind of counteract the HP loss from it but I’m not sure if monk/rogue would just work better overall for my damage since that seems to be my main issue currently. Curious to hear from more seasoned players what the best route is
