the ekko hate and the "ekko is broken/OP/imbalanced" threads need to stop.
i see so many of these threads of people getting pub stomped by a champ that has been out not even for a week now. so i am going to explain the MANY problems ekko has right now.
first things first, i want to address the "tons of damage" ekko deals. he does NOT deal any more damage than a fed
or even
. people that are bitching about his damage are the same people who bitch about lb/kat/fizz/akali/zed. GD simply hates burst champions and want them gutted, this is FACT.
but that asside, lets look at his damage.
Passive: 「 27 / 39 / 51 / 63 / 75 / 87 / 99 / 111 / 123 / 135 / 147 / 159 / 171 / 183 / 195 / 207 / 219 / 231 」(+ 70% AP)
it takes 3 hits to even get this damage off, but aside from that LBs Q does more damage if you proc it with W or E or another Q.
Q: 120 / 160 / 200 / 240 / 280 (+ 80% AP) 」alone this does about the same damage as an ahri Q. the reason you may see it do insane bursts at times is because it triggers his passive. if you see 2 rings beneath your character, do not get hit by this skill. if this doesnt trigger his passive it actually does very mediocre damage.
E: 50 / 80 / 110 / 140 / 170 (+ 20% AP)
below average skill damage. just like with Q its only used to get his passive to proc which makes the small burst from his E that much more powerful. alone it does almost nothing.
R: 200 / 350 / 500 (+ 130% AP)
his R is completely balanced believe it or not. the people who die to it are the idiots that stand on his ghost. funnily enough those are the same idiots who stand on azir's soldiers as if they dont exist.
TL;DR: ekkos entire burst depends heavily on him procing his passive. if he cant proc his passive multiple times on a target then he has no burst. this is why you see him go in and out alot because his passive has a 3 sec CD. this means he has counter play unlike kat who just jumps in and kills everything around her or LB who goes in and just flat out kills you without warning.
next thing i want to mention is his TERRIBLE laning phase when matched against certain champs.
see these champs here?

they make ekko a very very sad boy. darius, swain and malz are the worst in the line up. he CAN NOT even cs vs these 2 champs. like he litterally cant do anything at all. its not like zed who can just use his shadows to CS, its not like fizz who can just jump in and kill you once he gets tired of malz/swain BS. ekko has to just sit there and take it and HOPE that his jungler is not complete trash and lets the malz/swain overextend for 20+ mins without a single gank.
cho/garen are tanky enough to deal with his burst + they have pretty long silences to stop his #LCSBIGPLAYS. riven just flat stomps him. more reliable stun, more reliable shield, and instant non 3 hit damage.
