Kalista and Jarvan 4's ultimate

Ok so Kalista isn't meant to pass through walls with her passive, BUT Jarvan 4's Ultimate creates a wall and Kalista can use her passive to go through it. So, is this meant to be this way? Becuase Anivia's wall is "thicker" and Kalista can't do this here, so I feel it's unfair that J4 ults her, and she can just jump out, like nothing happened. So if Rito made it this way, I think It should be nerfed somehow given the fact that Kalista would be the only ADC, or only champion, that is able to escape from Jarvan's grasp "just cuz": Thug Life
