ONE SMALL change to his passive would make Jungle Ekko feel more viable again

Have his Z-Drive passive only be able to proc every 5 seconds on champions, but give him the original 3 seconds against Jungle monsters, that way he can still clear well and doesn't feel like he falls behind early in every single game, while still not being incredibly annoying with his sticking potential against champions.

I think one of the things that makes Ekko so appealing is his ability to play three different roles and fit into a lot of teams due to this. So please, throw him a small bone.
