I played the game up to t3 at release and I'd like to make a return, can you suggest me a pretty balanced server? I am going to play destruction if there is a good one.

And, are there yet crappy classes like chaos magus at release or are they pretty much balanced nowadays?

Europe- Norn or Azgal. Both are balanced, I think. I can speak for Norn.

NA- Badlands. Dont waste your time elsewhere imo, though T4 Gorfang used to seem balanced when I was there but that was a year ago.

Crappy classes? Each to their own imo. Magus and Engi got good buffs not so long ago.

Not many servers left, pick one where isnt xp bonus cuz they are low population
