˄Height advantage is HUGE in combat especially where you have range elements be it defense, accuracy, range, moral, everything it's the biggest advantage you can get combined all of those and you can stop huge numbers...
So i'm totally ok with a bigger numbers granted. I would be more happy if you could go prone to counter it but that would be asking to much just like overwatch. IF you were on ladder in the middle of nothing i would be fine with just range bonus...:)
As is, i know how important normal terrain height advantage is i mean +3 or whatever would be fine as well but that's not gonna fix the problems you have with combat. Because IF highground advantage is to big, then advantage it's to big for everything. Due to the things i said before Hp and stuff... i was exaggerating a bit but still you get the point.
Like i said already they need to fix jump/disengage first before anything else. If you wasted 1 or two turns just to get to high ground no one would cry it's op.
But it looks like nothing is gonna change anyway so it's all pointless... and is just random forum fighting. So i'll use my Height advantage thank you and hope for mods and really hard and not a gimmicky Nighmare mode.
