I've been debating it. At the moment I'm more focused on the sheer damage potential she has, but the Q crossed my mind a few times. I'd think it'd probably be a medium speed skillshot projectile, comparable to Blitz's grab in speed and size. It would be able to hit minions, but out in the open it'd be much easier to hit considering the slow it stacks on top. The debuff durations could probably be adjusted downward a tad, but yes, if you're under a Q barrage they're going to stay there regardless. Luckily blind only applies to basic attacks, not skills, so there's some relief there.

Something else to take into consideration, she has base stats that are comparable to Sona and Leblanc. In otherwords, pretty darn low. She'd pretty much rely on her Q spikes in a 1v1, and her E in a team fight situation. Also due to the way the passive works, if she intends to go in she needs to pick her technique ahead of time. Swapping from rotation to repetition spiking is easy enough (good for a finisher on a runner or whatnot), but going the other way isn't as easy. I intended for the added cooldown from the passive to mean that if she uses a spike combo, that ability is probably shut down for the rest of the fight.

It's funny how her concept disrupts her balance this hard. Adding a resource or cooldowns to each skill would probably make it easier, but the way it is now it's tricky.
