I know how to fix the Est Coast Issues!
There could be an artificially applied latency for each action which is equal to [100ms - ping] If the value returns zero or negative, no latency is applied. This way, everyone will be playing as if they have 100 ping, so the fight will be fair.
But wait, this is a terrible idea that no one would legitimately support! Having 100 ping is too detrimental to force upon someone just in the name of equality. In fact, ping matters so much that the average difference in ping between a bronze and diamond player is 34. http://www.elophant.com/league-of-legends/charts/tier?region=na&period=week
