Since Cassiopeia's VO is being redone, will she get some gameplay changes too?

It's no secret Cassiopeia isn't as popular these days due to the mobility meta. Yes, she gets movement speed from her Q if she hits a Champion, but that's not the problem. The problem is that she has to stop to cast anything, and due to her being short-to-medium range, that can be a death sentence for her if she stops even for an instant. Add on that her combos are unforgiving in terms of difficulty, and that sometimes your E will miss hitting poison due to a time-out, and I think she could use some love (and not a tryst).
At the very least, Cassie's E should be castable while moving. You want her to be able to utilize that mobility of hers? Then stop making her stop to shoot! If that requires some nerf to compensate, I'm sure we can live with it. But that clunkiness? Impossible to live with that stumble.
Additionally, have you ever cast her E, but the poison on the target times out before the shot hits? Worst thing ever. Either the poison check should occur at the moment of casting (rather than the moment of impact), or the projectile speed of Twin Fang needs to be WAY faster.
