Yea so you're litteraly asking not to enjoy any verticality in the game^^
Advantage is not the only thing highground could give as a bonus.
No more advantage for highground = many more viable and balanced possibilities to have an advantage = more tactical decision/choices.
Highground could give other bonuses than advantages. +2 to attack rolls, +2 to AC, better range, with a few adjustment to the maps it could also be a kind of "cover" mechanics (because you can often hide or break the ennemie's lign of sight).
What would change is that highround and/or backstab wouldn't probably be enough to have a satisfying %to hit. Players would have to be creative to increase it (there are many ways in D&D both for melee and ranged characters including basic actions like help, shove to prone, hide, flanking,...)
Well that's what apparently passes as a fix in BG 3 not to use it. Why i don't know but that's the take from Larian so far.
THere is no reason to be creative when best option is always just to nuke stuff due to low HP. Why cast bless or whatever when you can just use something that will give you more damage you only have 4 Concentrations to use and low action economy. Even stuff with more hp dies fast..
And without good highground bonus i will not even bother with that. Right now it's the only rewarding thing in the game. When i get to highground i get the feeling a actually did something tactical. Maybe that just me. But i do agree that backstab feels like chees due to jump/disengage. Melee are now just frogs..:)
