Locks have got it so easy at the jumping section. Titans too.
Just jump away from the walls as if you're gonna fall and then glide back in
I think warlocks have it the worst, just by the little thin ledge part alone, Titans and Hunters can "bail out" as they're falling, warlocks can only fall faster.
Plus with that thin bump part there are small miniscule areas that can screw you up, from hitting the ceiling as you're trying to jump away, a tiny crack in floor that you can fall through if you move too cautiously and another crack in the ceiling that can push you too far out to recover from, I'd like to say I've seen it all, but under pressure people find new intricate ways to mess up on that part.
