Note that these include matches with players not taking flash as summoner spell . Flash is hovering at 97 %. That shows that once every 4 matches , there is 1 player not playing with flash . I don ' t know at what MMR that would happen but at 2000 aram MMR it is like 1 in at least 10 games to get a player without flash ignoring hecarim . Anyway , those would take exhaust heal , snowball exhaust , snowball heal . I would say not getting flash is an auto lose very low win rate compared to with flash and that might skew a certain summoner spell . I don ' t think it will skew snowball because it has a very high pick rate . It would be interesting to see winrates with flash and without flash on each champion . <| sep |> It only works in the Gauntlet because you can ' t die , in any other situation this doesn ' t work .
