Maybe this is a problem with past updates or some PC's ability to run Bg3. I don't have any problems that are noteworthy...?
Of course, the stealth issue which makes enemies sit still and snarl instead of investigate exists. That's probably not the topic, though.
When horde action is triggered, 2/3/x enemies moving at once would emphasize that there's, well, a lot of enemies! Seems like a great idea on paper, at least.
Outside attacking the goblin camp outside all at once, the time has never really bothered me, though. Not because I like waiting. It's just that I observe and calculate my next move on the enemy's turn. If you don't do that, I can see it being uncomfortable.
