So, I stood there..dueling a Maokai for a solid minute or two as Tankko.
And we could've kept going with the sustain war but he ran out of mana so I chased him down.
Does that make Maokai AND Ekko an issue? Mao probably kept going for a lot longer if he had more mana.
But in any case, Ekko is actually STILL ridiculous, nerfs or not. I think this is a case of bad champ design...or something. I don't think I even utilized W's stun. It was just Q-E and what felt like 50 autos. I didn't need to ult either. After he gets Sunfire/Visage/Iceborn with Grasp, he rarely dies unless he's cc'd to high-hell.
I actually felt bad afterwards. I felt like I killed a kitten or something.
What even beats Ekko? Once I/we beat an Ekko cause he was AP mid (still building the tanky AP items), but a tankko? Obnoxious.

into Tank Ekko. I win lane every single time.
Can crush him any stage of the game. More damage early, more reliable sustain, and later on he stacks
very easily AND has his built in 25% armor pen while being very tanky himself
Sustain for days, a lot of damage and can steal tank stats
