High ground is actually a big part of what combats are and it shouldn't. It should only be a reasonable bonus and a tactical option... Not a systematic/cheesy mechanic.
I don't agree with this - personally think high ground should be a big part in the game. Shooting upwards should be more difficult and vice-versa, because that is how actual combat would work.
High ground is not really a feature in 5e because most combat encounters take place on a 2d map. That is what a DM can be expected to prep for a session. Whereas BG3 has a 3d map, why not take advantage of it?
