How disappointing would it be in a game with such a massive focus on verticality, if you couldn't fly or hover properly in the final release? No fly or levitate to get out of reach of melee enemies?
Scouting with a Raven familiar feels terrible when you're jumping instead of flying. You can't fly over a group of goblins. You have to jump on the ground right in the middle of them.
And climbing should be the means for PCs to get to higher elevation, not jumping around with superhuman strength like Spiderman. Jump distances are ridiculous in BG3, especially height.
