To All You People Who Think the FOX vs CG Decision was Unfair...
You are forgetting that if it was called a rematch, it would have been unfair for Echo Fox, so that doesn't solve anything. They had a 7 turret lead (CG had yet to take a turret) and a 10k Gold lead, in addition to one inhib and a baron buff. If you take that away from Echo Fox and make them start from scratch, just as many people would be calling the game "unfair." It was a lose-lose situation for the LCS officials.
Also, there is an NA LCS rulebook that vaguely goes over this kind of stuff http://esports-assets.s3.amazonaws.com/production/files/rules/2018_LCS_LACS_Rules.pdf
