Certain knockback actions affect a DRG during Sky High

Did you manage to test what happens if Blast Arrow is used after the DRG is in the air? Because my experience is that in some cases, I was in the air for like 2 or more seconds and I got pushed anyway. I don't think the application delay of Blast Arrow is more than 2 seconds, is it?

It's not possible in a reactionary capacity. Yes Blast Arrow has a long animation before the effect hits, so what you're experiencing is BA being initiated just before the start of Sky High, feeling like you're getting shot after the fact.

DRG's Sky High is collecting Ls for sometime now, since they changed the obvious blue ring to a shining red ring and did not increased movement speed while airborne. A kb while airborne is almost guarantee you're missing your target.
