We all assumed that at some point Larian could feel the need to test the balance of what's arguably the MOST IMPACTFUL level up in the entire game's progression curve.
So far, we all have been proven wrong. Seems like Larian is perfectly happy with just running the EA with four levels as a cap. Which is a bummer since 1) they are reached rather quickly 2) many classes barely feel any different before level 5 hits.
