At this point, unless Larian actively screws us over, we can fix this game...
Hmm, hopefully you guys also figure out how to get rid of the 'Target Too Close' malus, and reduce 'Threatened' range to just whether or not you're eligible to take an opportunity attack if you move away. I am not entirely sure modding out height advantage is a good idea without those two being addressed at the same time, or else it's still going to be a race to high ground and needing bonus action shove just for the simple idea of staying a mile away from enemies to avoid the threatened penalty at all times.
