*frustrated hand waving* Why is this capped at 4?
Because that’s content they provided for EA access. With level cap for full game being planned somewhere above level10, level 4 doesn’t sound that bad.
They still provided limited selection of classes and races, so it’s not inconceivable that they didn’t finish working on higher levels either. Even so, it is less a case of what Larian can cram into EA, and what they want players to have access to. Exact reasons are their own.
