Indeed it is a strong skill. The mobility is great and the early game damage is wonderful paired with animation canceling for sure.
Oh, was it a perfect block that dodging strike gives if timed correctly?
Learn somethin' everyday, eheh. And yeah, takes a while to get the hang of. It's strong in experienced hands. Not so much for those who aren't (speaking from experience. Lotsss of poorly timed dodging, ahah.)
And yes, it is simply the description that is more my issue. It's just, logically (at least in my mind) it should follow through to that you aren't target-able during the dash animation. Thus invulnerability would make sense in this respect. Logically. Right?
