I think it does matter though. Specially in the fights where XP is the only reward. To then get slapped in the face and walk away eith less xp then a normal goblin should give is kind of insulting and gives almost no incentive to do these fights...

If you mean it doesent matter in the EA because theres a lvl cap in place.... well sure. There is. But isent testing to see what lvl people reach if they do everything important to do as well?
