Jayce AutoAttack Bug

Over the past 2 most recent patches jayces Auto attack has changed significantly, As a jayce player it is extremely noticeable to see the sudden change in a motion you are so used to. The change in feel of the autos is drastic with them being much slower and somewhat invisible, also the sound is now out of sync with some sounds not even registering when you auto. This extremely detriments gameplay and allows for many now canceled autos. I do not think this has been intended of the the past 2 patches as it has not been in any patch notes and now the auto has changed 2 times in the past 2 patches.
