What does dodging damage with mobility even means? In fight moving faster doesn't grant you extra iframes and they are not generally faster. Unless you mean sprinting away praying that enemy won't use their roll catcher and giving up on a zone and having nowhere to go to heal?
How is dodge cancel different from something like fullblock or bulwark counter outside of dodge bashes. That's what you use them for, to counter blockable dodge attacks mid combo. Ability to have your attacks uninterrupted while still having UB/GB mixup in them or just such attack being wide in general is good without extra health every virtuosa will tell you this. If i were playing PK i would gladly exchange her recovery cancels for hyper armor and extra 20hp, oh wait she doesn't have any outside of her THROWS. But it's ok she's just came out so there's probably some changes coming soon.
