They are desperately trying to give players ways to actively get advantage to reduce the amount of missing in combat.
But the easy advantage messes up the balance of the D&D combat and magic systems. And I agree the jumping to backstab or disengage (or even climb) is really silly. I'm surprised someone ok'd it for the EA. Imagine how ridiculous the fights would be if the AI was also smart enough to leapfrog over the PC's to backstab them. Any PvP would certainly look like that.
I wish they would make the AI go faster instead of messing with the rules. Missing wouldn't be so frustrating if the AI turns would go faster. And there are much better ways to increase hit rates, if that's even necessary in the end.
