To me, it fell into the same trap basically every cRPG falls into; late game combat is a chore. Once the number of enemies and skills you have to juggle gets high enough, you can't realistically use real-time on the harder fights, but you can run into so many enemies that turn-based takes forever.

I don't even really mean that as a criticism of Larian, since nobody else ever managed to fix that issue either. It's a big reason why the genre died off for so long.
