Well for me level 4 cap is not a disappointment the thing to remember about the EA is it's just away to fix as many bugs as possibly and it's not going to be easy to level up like in NWN1 and NWN2 in BG3 and the level cap of the full game is level 10 so we are getting just under half of the levels in the EA
