Jump can stop any knockback. It tracks your position based on when you hit the button and returns you to that spot. If you time it JUST right, you'll cheese to the point that you'll only get knocked back a very tiny bit and the rest is negated. The timing is pretty tight so I tend not to try, but I suppose I should.

I usually just hold DFD on my opener in A3 and use it after the second wash away for the chase. I absolutely hate the delay that's inherent in turning around to use Elusive Jump; the only spot in current raids (that I've done so far) where I use it... I'm on 0.5 in A1S so I elusive back to it after my first B4B combo on the not-0.5, and I use it after blowing up my first gobtank in A2S to get back to the other tanks and hop in before Wave 7 so I can squeeze in as much damage as possible on the widow.

That said, I would pay SE money to make me an inverse of the /facetarget command so I could macro it to Elusive Jump.

I might actually end up doing the Doom Spike "cheese" there... I have an excess of TP assuming healers don't let me die to Sluice in P1, and the amount of GCDs I have before Equal Concentration is awkward as hell... Also makes it so I'm focusing less on attacking while I do Digititis \o/ win/win/win. And yeah, pants are a huuuge get. I'm stuck in loot hell - 3 weeks without any meaningful upgrades (Eso boots being the only piece I've gotten in the past 3 weeks that I can actually use in A3S) and next week I STILL won't be changing gear unless literally any one of the four pieces I don't currently own drop for me. The week after I gain about as much weight as when I purchased my weapon, though, so I can't complain TOO much. (Eso chest+head+gordian neck+2 coats+I can use my eso belt)
