Ekko needs power shifts

With Ekko's decent, or rather really good Base Damage he is now being played heavily top lane with a tank Build and still dishing loads of damage, and with his Ult being a much stronger GA, and his insane dash range he is just wrecking havoc in every game.

I think Riot should nerf a lot of his base damage, and increase his AP scaling. This way Ekko HAS to build AP if he wants to slap out loads of damage, otherwise he is only used for his utility.

TimeWinder should go from: 60/75/90/105/120(+10%AP) to 30/45/60/85/100(+30%AP) Outgoing Incoming damage: 45/70/100/115/160(+75%AP)

I dunno, I'm just tossing out ideas, possibly REALLY bad nerfs if they did what I just posted for an example on his Q, but I hope that gives an idea on how he should be "nerfed" or rather.. Have his power shifted from raw base damage to him actually having to build AP to do crazy damage.
