Last I played I had a 60 beserker,58 mystic. Is the game worth coming back to?

yes and no

rest is for you to figure out

Depends if you can withstand the poorly optimization of this game. Overkill PC still isn't good enough for it.

I was just really annoyed with the randomness in pvp camera angles really annoyed me and the targeting system. Also having too many useless abilities. Is it still bad?

combat system and gameplay itself isn't bad..and i'm not sure what you mean by randomness in pvp camera angles and this isn't WoW..Tera doesn't offer auto-instalock skills

zerkers have never had worthless skills, what are you talking about?

Leveling a Brawler on mt. Anyone want to add me? Name is Bulmalol
