Ekko's weakness.
No sarcasm. Here is what i notice. If you catch him with a gank, his pants are down, and any damage you get on him will stick. The way to gank him is to force him to back. Hes squishy and has no sustain. His shield takes 3 seconds to charge anf thus he has no way pre-6 to escape or turn.
That being said, a 300 range dash is kind of tough to take down in a short lane though with lb and zed in the meta, i'm sure you junglers have some ideas. Past that, Ekko struggles against people who can poke him down. Treat him like Tryndamere, get too close and he will all-in, if you are ahead, poke him down until he burns ult or backs.
The problem with this is that the entire goal with playing against Ekko as his laner is to avoid interaction with him, unless you are a jungler or tank. I'd honestly like to play the Ahri matchup on him. Cc and dashes to avert his damage, and sticking potential if he misses his shots. For junglers, i think wukong is ideal. For bot lane, Braum messes up Ekkos W and Q and the braum stack should remain post-ult. From top lane, maokai, hecarim, Singed, Vlad, and Riven will mess up his day by midgame or sooner.
Best of luck!
Additions...Jayce, Malz, others with good waveclear/seige.
Jayce does well against him too. He knock him back if he gets close, and just auto attack.
You don't have to run a full siege comp for Jayce to work, though. A lot of siege mids can be smacked in just about any comp because they aren't terribly weak at any one point in the game.
I would imagine Galio ruins him, too. Malz could probably work as long as you shoot first.
Got a post from Yenn, a longtime player. Definitely worth discussing.
I can't think of any mid champion that can lose to Ekko, unless they misplay really badly.
Melee disadvantage + no anti-harass (sustain, more reliable shield, etc.) + not AD (can't build life steal) makes it impossible to CS in lane, against most champions. Even if you don't kill him, you can easily force him to recall and miss out on a lot of CS, putting you ahead.
The minion wave will rarely be in his favor, because his clear is weak and expensive. Most enemy mids will have stronger clear and some mana sustain.
The real problem is that his kit is built around KSing. His damage is incredibly low unless you're already at low health, and relying on movement speed to disengage is countered by any form of CC plus slows, which most champions have. His stun may as well not exist; you have to not be paying attention to get hit by it.
is a great counter. He dashed on me, I ulted him and he's gone.
