[GAMEPLAY] Jarvan IV's Ultimate Allows Players to Pass Through Incorrectly!

This season, I started playing a lot of Jarvan IV. I really enjoyed the changes they made to his ultimate, namely the repositioning and the AoE damage. However, I have now noticed a HUGE problem that has invaded lots of my games, at times even back-to-back.

Jarvan IV's ultimate lets people escape. It lets people escape without using appropriate escape abilities.

I have seen this happen in at least two different ways. The first is the most common. You ult onto an enemy, (Vayne, Blitzcrank, etc.) and start to fight them. Then, the next thing you know, they are walking THROUGH the wall of your Cataclysm. Blitzcrank can do this by popping his movement speed buff ability, and rubbing up against the wall. He will pass right through it. Vayne can do this by using tumble against the wall, which will put her partially inside the wall, allowing her to wiggle through it.

I have seen other champions do this as well, and I think it is mostly related to increases in movespeed having some strange interaction with the wall itself. Perhaps the wall's thickness isn't enough units. Regardless, this is an extremely frustrating problem that happens sometimes several times in the same game.

The second issue is like this: you run toward and enemy, shout DEMACIAAAAA, and leap onto them. Right before you land, they reposition slightly. When you hit the ground, the walls of your ult come up.....with the enemy inside of them. They are actually INSIDE the wall, once again. At this point, they move sluggishly as they run away from you, passing right through the wall. It is extremely frustrating.

This issue is very annoying, and I am not positive as to what causes it at a programming level, though I think it has something to do with how the game registers the ultimate as terrain, and how thick it is. I think that maybe if they increased the thickness of the ult, it would fix a lot of these issues. I hope that Riot sees this, and looks into fixing it as soon as possible. Thank you!
