Need and advice about exping.

Hello guys. Does anybody know any good spots to lv up subclass after lv 50? I'm leveling a dark avenger.

 

As far as I know, what worked to me was,

in case you are not higher level than 51: Town of Oren > NPC Flutter > Quest ''The outlaws are incoming''

in case you are between level 52 - 57: Town of Oren > NPC Mouen > Quest ''The reason one cannot wait''

in case you are between level 58 - 60: Town of Aden > NPC Paterson > Quest ''Defending the Forsaken Plains''

I know you are asking about good spots, but, I think would be best, or at least faster, to follow these quests.

 

Thanks for information.
