I made a mistake and chose the perk which gives you more XP per kill/quest completed and have leveled up way faster than i wanted, im almost at lvl30 and havent completed a single main quest mission.

Can you reset the lvl cap or increase it?

I′m guessing some of the thrill of playing the game is lost when you have reached the lvl cap.

Reload a save before you took the perk ?

30h after i took the perk?
