Since you're adding Camille to the game, I think a friendly buff to J4 is warranted.

As we all know, it's rough when you have a champion you like with a very distinct ability that looks like he(or she, or they)'s about to be thrown in the dumpster in favor of the new hotness. <- old and busted here could use a small gesture of gratitude.

I therefore recommend that you add a small buff to his ultimate, something to remind his teammates that Jarvan is helping in ways that Camille can't.

Jarvan should grant a bonus of +5 movement speed to allies that are in the radius of his ultimate when he uses it, for its duration. Naturally, of course, the name of this buff should be "Jarvan is helping."

It's times like these that we as a community should come together to support our fellow players. I personally can't stand Jarvan, but for the J4 mains out there, I salute you. Have a great day.
