Larian Studios Forums Divinity: Original Sin 2 Divinity - Original Sin 2 - General Stat inflation is downright stupid.

I get the impression that the stat inflation, and many other issues, is a consequence of the game being so long that Larian never really was able to test it by taking a party from start to finish. Even without game-stopping bugs, it would be hard to finish before new stuff gets added and the internal builds changed.
