J4 passive

As a J4 main I feel his passive is very lack luster. Apart from the Jarvan nerfs because of him being "meta", J4 is still in a tough spot as a champ. He either goes Tank or ad when in game. Bruiser is okay, though tank or ad heavily out ways it (IMO). Though to my point, Jarvan's passive needs something. Look at Jarvan's kit. Q- armor shred/knock up, W- shield/slow, E- attack speed, R- cataclysm, passive- 8% (as of now) health based damage. Just more damage on his first auto attack? I think there is a better way to show him some love.

I believe that J4 should have a passive similar to Katrina's. Though, for every knock up, his q and e get refunded by 1 second(s). J4 has an easy, yet hard knock up to land. The knock up isn't point and click and you need to set it up correctly to land it. It will make top Jarvan more viable because he can trade. His damage will be nerfed because the removal of his passive. Unless, Jarvan gets health based damage on every knock up. I wish they didn't nerf my boy to the ground because he became "meta".

Just my view on this what you guys think?
