When I first saw it I thought it would be useful as sort of a short jump to compensate for her normally floaty ass predictable jump that gives the opponent like a half hour to anticipate. But the recovery on the V-Skill seems just as slow anyway so it doesn't really work like I was hoping.
The main issue I have with Chun's V-Trigger is that a lot of other V-Triggers create new opportunities to open the opponent up, in addition to allowing the character to do more damage. Chun's V-Trigger doesn't really do this. You could argue the new combo opportunities open you up to use the df MK overhead more, or that the blockstun increases her overall pressure (it does). But the fact is, the way you play her doesn't really change. She's still a character that excels in the mid range. So while you're playing footsies and whittling health down, your V-Trigger is draining, and you may not even really get anything out of it. Getting an extra hit out of a few st MKs isn't worth the activation.
I'm also a scrub so maybe I just need to get good. But my feeling right now is that her V-Trigger is more useful in combo videos than actual matches.
