Seems strange they'll cap so low, unless the game will be shorter than expected or they nerf xp gains. Feels like without the cap at 4 in the EA we could already reach 5 or 6 during or after the Underdark.
I couldn't agree with you more and that is why I'm surprised they have it capped at 4 right now. In my current playthrough, I've already hit the cap and I've not done any of the Underdark or the goblin camp.
Hoping in the next update that they not only fix more of the bugs but give us some new game play and raise the cap from 4 to maybe 7
