Tank Ekko's Real Problem

It's not that his utility is too strong, or that his base damage is too high. I mean, it's why tank Ekko is strong, but it's not why tank ekko is a thing in the first place. People build him tank because_ they don't have enough incentive to build damage. _

Now, most people who have played Ekko would agree that it's pretty hard to land a combo to assassinate an enemy ADC as a glass cannon. By the time your Q comes back to you, you'll probably either be dead, or the enemy would have moved out of the way. And forget about trying to catch the enemy with your ult--it takes a intro bot to step up to your hologram and just chill there. His kit has huge damage and utility, but he doesn't have access to a HUGE portion of it against any competent opponent. So, why build damage? Think about it this way: if you were playing as the Scuttlecrab, would you rather get a million AD, or a million health? Of course you would want a million health, because a million AD won't do jack shit for someone who can't hit anyone. If you can't pose a significant threat to anyone anyway, you might as well get tankier to soak more CC and damage from the enemy team before you go down. If we continue to nerf Ekko's base stats and utility, we won't ever fix him. He'll just be a worse champion overall, but he'll still probably build tank, because there is no point in building damage when your damage is so god damn easy to avoid.
