. And turn based fights in D&D5ed are very smooth and fast so you don't really lose dynamism.
If that is the case (I haven't ever played PnP) then it would seem to me that 5e PnP combat has not been translated well into BG3. Is there so much emphasis placed on gaining the high ground and jumping behind opponents in PnP? Genuinely curious.
No, because the implementation of Jumping is not correct to DnD, I believe is the general thrust of things.
