Syndra ult issue

I was in a bot game, and something weird happened. Now, before I continue, I've had internet issues for a month, but I don't think it's related to that. But I was in a bot game as Syndra, and I ulted a Rammus and killed him. Then, my screen looked like it lagged, but my ping was it's common 33. Earlier, I had ulted a Veigar, but it didn't kill him and I didn't get the issue. I thought it happened when I killed someone with my ult, but towards the end of the game it happened when I ulted, didn't kill with it, then used my push and got a kill. I think what happens is when you get a kill with a Ball from Syndra's ultimate, or interact with it in some way, your movement gets, for a lack of better words, choppy. It's only when the ult balls disappear that you get back to normal, but for that range of time it's really disorienting. I know Syndra has had issues in the past, but I never experienced a bug until now. In short, when you ult as Syndra and the balls are used to kill someone, even without the ult itself killing, you get choppy movement until the balls from your ult disappear.

is buggy again. So tell me this, Riot, because I really want to know this. Has anyone else given you guys this issue recently? I don't know for sure if this is a bug with Syndra, or my computer just having more internet issues, so I'm curious if anyone else has this problem.
