So instead of strategizing about what spells to use, the player just spends their movement. There are other positioning choices that could be made as well if the player wasn't over-incentivized to move all their ranged party members to high ground.
In my opinion, this is more an issue with being low level and lacking a substantial spell roster, rather than height advantage. Ranged character being incentivized to seek out high ground is a good thing as it promotes more tactical combat than would be possible without verticality coupled with increased mobility. I do agree with all positional advantage is over-incentivized however, so much so it will force Larian to make some significant homebrew to Barbarian and their staple Recless Attack ability for instance.
That said, I take much more issue with flanking/backstab advantage than the height counterpart. At least enemy AI focus on gaining height advantage while they pretty consistently fail to take advantage in melee. Besides, moving to the back in melee constantly is EXTREMELY gimmicky in a way that reveals turn based movement/combat (that I actually prefer) as a highly unrealistic approximation of combat. It downright hurts immersion in a way ranged advantage simply doesn't.
I didn't expect classes that are range-dependent to become Pidgeon-holed. In tabletop DnD 5e, the fun of playing Sorcerer, Druid, and Wizard in DnD is that they are strategically diverse. You make situational choices that benefit the party.
In Baldur's Gate 3, Fighter can solo a Bulette and wizard is stuck here casting magic missile. Ranger needed buffs, but don't give non-martial classes the shaft. Non-martial classes are denied being fun in the current meta. Even Druid is showcased as being "Wild Shape is amazing and you're an idiot for trying anything else."
I don't want a game where Wizards and Druids are one-trick ponies. When they're supposed to be the opposite.
To be fair, one of the very strongest builds is a Wizard specced out as a fighter with the appropriate magic items, they become the most versatile builds in the game able to go toe-to-toe with anything or stay at range. I have seen even regular built mages win in combat fighting both the Bulette AND the two Minotaurs at the same time.
