Vi's Q Interaction with Grounding Feels Wrong

Grounding is supposed to stop dashes, but the first part of Vi Q is a self slow that she charges. It feels strange that she cannot be charging the abilty while grounded, preparing to release it when she is no longer grounded or failing if she tries to release it while grounded.

I always felt like it should work this way with roots as well, sure she has to stand still, but why would that interupt her charge?

Just a thought I've had for a while as a Vi main, I'm curious what other people think.
