I agree, and I have suggested similar changes (for both height and flanking). This kind of adjustment will be forced upon Larian once they realize their virtually guaranteed flanking advantage have royally screwed Barbarians and their staple Reckless Attack (you gain advantage on attacks, but enemy gain advantage attacking you).
Ha, sorry to disagree with that sentiment, but I am pretty sure Larian will have no problem with Class abilities like Reckless Attack.
They will just change it to something like Double advantage or giving you one more attack or shoving the enemy across the whole map or making an animation that you kick them in the butt (literally), because that's what is super funny.
Sadly Larian just doesn't care for a balanced system, because apparently they think that would be mutually exclusive with their vision of fun gameplay.
And people like you and me have to deal with it.
