there are just to many possibilities to get advantage and disadvantage in bg3.
in 5e you need to actually make sacrifices to get advantage like:
shoving prone (using your action)
reckless attack
spells like fairy fire
advantage is really strong but in bg3 you can just walk around your enemy and backstab them
Are they gonna redesign reckless attack, fairy fire, true strike and etc? they feel useless.
