It’s definitely not overtuned. In easy mode you get max HP let level up and enemies deal less damage. Balanced is where the game respects the rules. You have every advantage with height manipulation, positioning of your characters, having a long rest before a combat encounter after reloading if you didn’t see it coming… All of those things can’t be done in tabletop.

It’s fine to want the easy mode, nbd, but saying that it’s overtuned is a stretch when comparing it to the tabletop version of 5E.
