I don't think it really spawns that early. Though I know the map, I can get to the top of the stairs before the motivator appears while the Hale is actually trying to get me.
Its just a matter of knowing the map, once people are used to it and understand the traps better, then it won't be as much of a problem. Not nearly as bad as slay though, lol.
I have a feeling a lot of the stalling is at the doors on the first floor though.
