I'm an Ekko main. AP Ekko, specifically. Ill tell you why hes acutally really fun and versatile. First of all, mid-late game his cooldowns are very short, Q and E about 3 secs and W like 7, ult about 50 secs. You obviously don't understand the appeal of him. The point of his combo is that once you got it off, the enemy should be pretty much dead after said few autos. Hes a delayed damage dealer. His ult is also one of the most badass in the game. If you pop that into a group, you will do 3/4 of all their HP. His W can set up some amazing plays, and he is extremely mobile from his E, with the roll and TP, and passive speed. I didn't see much from Ekko until I played him, and after all this time, I don't regret it. If you snowball even a tiny bit, you become this unstoppable mobile assassin, who is just running around, blinking from foe to foe and POPPING THEM. I cant really explain much more from here, ill leave you a link to an Ekko video, maybe you can see some of the badassery he can do. https://www.youtube.com/watch?v=eyfN9CWNBRI
