Gameplay Bug (Jayce R)

So, today when I was in pre-game lobby, someone wished that I not play (Jayce) because every other R cast (I think when switching from cannon to hammer form), it causes all allied players to "jump" or "skip" a few frames. I have never noticed it because generally I am focusing on myslef when I am casting R, but I payed close attention when the game started and we were running to lane and could definitely see that all (or most) allies did jump a few frames every other R cast. Our Ryze mentioned in the post game lobby that "those skips killed me inside early on". I hope to see this addressed soon, as Jayce is one of my favorite champs to play! Thank Rito!
