DON'T. BUFF. EKKO.
WTF is wrong with you? He's already waaaaay too strong and with no options to play against him.
EDIT: Jesus came on today and this was a pretty big thread. Now the salt of my previous game (Where Ekko had got 4 kills from my Kog jungle without me dying once, despite me spam pinging every time Ekko stepped out) has gone ill give more details on why I hate him. His Q is very easy to dodge from long range but its power is the ability to almost one-shot minions waves starting very early on (and he will usually use it after getting close with E and the slow attached is devastating and undodgeable). He just shoves, roams, shoves roams and unless you can match his roams or push back you're fucked. And his ult really doesn't need explaining losing fight? hit R. Win fight. Obviously not true for all situations but yeah Ekko really doesn't need any kind of fucking buff.
(and more).
can gain back tons of health at low HP, but is extremely immobile and risks a lot on it landing.
has to position since its his only safe dash without Qing something. Not only does Ekko heal for a base amount that's extremely strong any way you build him, but it then scales of a % of missing HP lost during the few seconds. That's MASSIVE considering you need serious burst to put him down early on, and in lategame if it isn't an assassin an ADC will have used a full rotation to attempt to kill him. He can immediately ult to respond to a failed burst combo on his side and his opponents to put him down, making sure that he can get a second attempt. Combine this with a built in invulnerable dash to his 4 second clone, + an extremely low cooldown dash on E, and he becomes nightmarish to execute properly. Interesting fact, it also removes any form of DoT or debuff placed on him in the last four seconds, meaning champions who NEED DoTs to trigger abilities suffer because Ekko can shake them off.
got nerfed to hell and back, and still sees play, but its because of how much power is placed in his ult.
old Yorick with Omen copy?
with his ghost not only resetting a target's health, but forcing the ghost onto his team. And lets not forget old
with her ultimate resets and damage potential. They've slowly been rooting these champions away from a lot of resets to HP and CDs because the value of these abilities are near limitless given a situation. A fed Ekko not only makes this a massive nightmare, but thanks to his massive adaptability and burst, he's frightening on all levels.
