I think you are completely incorrect when you say that a 5-15ms ping advantage doesn't cause a massive effect in a game of LoL. Even the greatest player of the game (Faker) mentioned the difference between "35"ms and the near 0 that Korean players are used to playing. Low ping is part of players' muscle memory in how they react to visual signals. Changing that slightly creates a big difference, especially in the early and mid game where the outplays are less strategic and can often be more mechanical. Even in later game teamfighting, the familiarity with latency between key/mouse input and actual in-game movement is mechanically intense (ex. auto-spacing in a close teamfight)
