I never enjoyed jRPG grind, so that's a strong "NO" from me. I don't see leveling as worthy goal within itself.
Biggest probablem I see that:
1) DnD system which Larian is adapting has a set level cap, and even at that they are not going to use all 20 levels
2) Unlimited available XP creates a major balance issue - do you expect players to grind, and therefore block actual content behind... well, boring grind? Or do you don't account for grind, so players who untentionally or unintentionally grind have unenjoyable dull experience?
