On Mitigation, this is balanced against DRGs additional HP recovery.
Drawing on the whole 'lancet' thing from past iterations.

That said, I do think something should be done, and if it's at all possible, I would like it if Jumps had an innate defence boost when in use.
Classically Jump takes you out of harms way for a turn to deal damage on the next turn. Instead, FFXIVs Jump is a hindrance to survival.
But given that they've shortened the Jump animations this would probably be too tricky to implement now.
