I understand the reason for stopping leveling beyond 12 because the new spells become so absurd it would make it almost impossible to implement without completely changing the game. Or breaking it.

But what about allowing leveling up to 16 but any level beyond 12 requires a multiclass. For example you could be paladin 12 and sorcerer 4 for example.

This would allow for meaningful power increases without the need for new spells that can't be handled by the engine.

Please Larian can we get another act as DLC, just allow us to level up a secondary class!

What do you think? Wouldn't this solve the problem with capping everything at 12?
