The time between Ekko's 1st nerf on PBE and his release is really short. Ekko was released on 28/5. On 2/6 he got 2 nerfs on PBE. I mean really, I believe this is a really short time between releasing a champ and deciding he needs a nerf. I think this brings us into 2 conclusions: Either Riot needs to do further testing before actually releasing a champ or Riot already knew Ekko needs nerfs when he was released but want to make lots of money out of him before balancing him because really, how the hell they knew that he needs nerfs after 5 days of his release??
