About the ekko buffs running through the pbe for patch 7.15

I know that the reduction to the cooldown of his e is a good buff, but that doesn't give ekko the chance to sucessed in other lane. Defenetely ekko was deseigned to be played not only as a mid-laner( be careful what i say: i said that he wasn't deseigned to be played only the mid-lane, the tools onto his kit make him releable onto top and jungle, i DIDN'T make this post so that i can propose changes for tank ekko, i think tyat was broken and of course i want to see ekko as a full ap assasin to rise again on other lanes and possions).

The reduction to the cooldown on his e might help him to become a god ap assasin on the mid and top, but not for the jungle, because of the amount of base damage nerfs that he has received. I know that if u buff his bases he will become a powerfull tanky diver again, but i propose a change that will help him be viable in the jungle without being to affecting his tanky builds.

So i propose to add that:

Make his Z-drive ressonence to slow the attack speed of jungle monsters by a percentage that won't scale based his levels plus will decay over it's duration. That change might help him in balanced way to be able to clear the jungle, without affecting him as a tank.

I would like u to comment below and your thoughts about my proposal buff.
