[GAMEPLAY] Jarvan Ult Animation Bug

My main champion in League is Jarvan, he is by far my favorite champion and while this bug isn't game breaking, it very moderately kills the "badass crown prince of Demacia" vibe I get while playing him.

It is a bug with his ult animation. What it should look like is him leaping into the air and slamming his lance into the ground, but what happens currently is Jarvan basically just "runs" through the air (literally moves his arms and legs rapidly as if he is sprinting through the air) and lands rather unimpactfully. While this is very minor and probably irrelevant to the average player, I play Jarvan in over half of my ranked games and the very quirky looking leap he makes while ulting has always bothered me slightly.

What his ult animation should look like (on base skin and warring kingdoms skin respectively, they fall under "spell 4" and "spell 6"): http://www.lolking.net/models?champion=59&skin=0 http://www.lolking.net/models?champion=59&skin=5

I don't have a solid example of the current bugged animation but it seems to me that ever since the end of Season 4/beginning of Season 5 this bugged animation has existed, so it has been quite a while but videos from before Season 5 showcase what the ult animation should properly look like. Based on the timing of this beginning to exist in the game, it seems to coincide with the time he got his visual upgrade right before Season 5 started. If you guys could somehow restore the proper animation for his ult that would be great!
