Better idea for a nerf to Ekko's ult.

I think that adding a 100 mana cost to Ekko's ult will definitely pull his strength down to reasonable levels, but hear me out. For character reasons, I think that Ekko's ult should remain costless.

The entire concept of Ekko as a champion is the ability to do something over. I mean, his reveal video was titled "Seconds," and the whole motif of that video was his travel-back-in-time mechanic. For this reason, it definitely makes sense for him to always have that ulti available (when off cooldown, of course). I think the best way to bring his ulti to a reasonable power would be to bring the AP ratio down a little bit and add a gradually diminishing slow. This would be way more in line with Ekko's champion theme of Punky Time-Boy, and would prevent the spell's damage from being keyboard-smashingly high while still bringing that "Utility Assassin" feel.

Your thoughts below, please and thank you.
