Ekko has so much damage
Specifically 103 + .25 AP DPS Compared to Akali's 315 + .72 AP or Ahri's 251 + .57 AP
Sorry, but if you die to Ekko from 100% before killing him, you may have a mental disability or be mechanically retarded. There are supports with more damage than Ekko. Chances are you're running around in circles going 'ERMAHGERD EKKER IS HURTING ME' or you're playing with your monitor off and walked into his ghost.
