I would have to disagree, I think height advantage should work with ranged and spells. It is taking advantage of 3D space, rather than 2D tabletop. But, I don't think say you on a small ledge just behind someone, and it gives you a melee advantage. That just doesn't sound right. There should be a slight benefit for ranged classes considering how OP melee classes seem to be. I have played a warrior, rogue, hunter and now playing a warlock, and melee definately have an easier life and do more damage it seems.
Some are offering a compromise because the current state is just too advantageous. Height gives roughly +4 to hit and +4 AC vs those who are below you. I don't know if you are familiar with 5e but one of the main design aspects of 5e is bounded accuracy. The goal was to reduce bonuses so it would be manageable all the way to level 20 and bridge the wide gap that often appeared between high and low levels. So at level 20, characters get +6 to hit vs +2 to hit at level 1. It's not a big gap, certainly not as big as previous editions.
From my understanding, BG3 will cap roughly around level 10. That would mean +4 bonus along with your bonuses for ability scores and magic items. As you can see giving +4 bonuses so easily can disrupt combat balance (you are doubling proficiency bonus at level 10). Other tactics are tossed to the side. It just becomes a mad rush to be on top of the hill. It' doesn't make for more tactics. It reduces them.
So some are asking for +2/-2 or even just -2 for height disadvantage. I don't even like that but either compromise seems better than what we have now.
As for melee, I am not sure why you think it's better. Can you explain with an example? Because melee seems to be more exposed to attacks than ranged. You can shoot them and swing a sword at them. Maybe it's because your melee characters tend to have more armor?
Of course, melee has its own problems currently because all you have to do is run behind someone and again receive that +4 to hit bonus with almost no cost.
And I realize Saito already responded to you. I assure you, I am not trying to pile on you. I am just trying to have a reasonable discussion.
