Yup, unfortunately it shows Larian screwed up the difficulty curve. Every class is a borderline demigod by the endgame, which makes me wonder why anyone in Rivellon was worried about the Void in the first place. After all a single one of my characters could have beaten it in their sleep.
Well, I guess that's one of the problems that the beta only featured Cyseal. The first map is probably the best balanced.
Anyway, the game is still big fun and possible future balance fixes could only improve the game.
