Syndra QOL
I'm just throwing it out there, syndra is just slightly op at the moment, so with that said. I think if Syndra is stunned or in stasis her ult if already launched should be frozen in mid air until she is out of it.
Why you ask? Thematically speaking, if she is stunned, how can she control her balls? Even in stasis her balls of her passive don't move just saying
