Jarvan, sure. Vi? Lee and Shaco are way scarier than her.
Vi's CC is trickily situational depending on the CC you have to counter it, while Jarvan's, Lee's, and Shaco's initiations are all pretty much free. Vi's damage is also conditional on her CC, while Lee's and Shaco's is not (and if you miss Jarvan's CC consistently you probably just suck or are playing against Faker).
Sure, post-6, Vi is scary as ass, but pre-6 the worst she's doing is blowing a flash if your team wards up. There's a reason J4 is the best competitive jungler in the game and Vi is a non-entity
