Hello,
I am tryin the demo version but the profile doesn't skip green color quests, It doesn every quest LOL.. so I think it is usless on more than 1x exp servers.
I just tried your demo version with Orc Shaman.
The quester doesn't turn in 2 completed quests at lvl 4 and it turns back to Class Trainer every level up. So I think it works just with 1x exp
