Oh wait, how does it work?
You get one tick ever 2-3 minutes.
You only get it if you win or lose duells in that timeframe.
You dont get it if you just stand around, run around, or stay in a duell and dont fight.
So either be active or dont get anything.
the xp is not great but it is at least xp on duel servers.
so you can go there and get some xp and gold.
battle and siege and probably dtv too are better for lvlgrind.
its totally ok for me that way.
