They need to balance out how do you get v-trigger ( apart from getting hit ) for most of the cast.
Take for example Necalli. Arguably one of the best characters in the game with one of the best if not the best v-trigger gets to build his with relative ease,the ground pound v-skill not only does it work for a decent zoning tool but it forces the opponent to approach ,and you don't want to be near Necalli. It's a win win situation.
Same can be said about Karin or Ibuki , good triggers , good v-skills to build them, can poke or combo into them.
Now take a look at Juri , Fang , Ryu. Bad triggers, bad v-skills ,even less opportunity to build their triggers without taking damage.
Either readjust all the v-skills and v-triggers , or give the characters that have a bad v-trigger, a good v-skill.
???? Juri v-skill is really, really good
