After killing the old hag and BEFORE entering the underdark i got levl. 4. So within act 1 i reached lvl. 4 very fast. Assuming the game will go until act 3 maybe a level cap at level 10 would be ridiculous?
Furthemore i saw a lot of vidos on YT where the only way to win the hard fights later was to push down the foes to the abyss. Will i have to cheese to win the hard battles? The game looks sometimes more like a climbing/jumping simulator than BG.
