Challenger Scene solutions?
There have been several games where teams have to forfeit matches due to internet connectivity. DDos and other issues have been claimed as the cause and Riot and the League of Legends development team just dont have enough control over the internet service providers to prevent or alliviate DDOS attempts.
But there are ways to avoid the DDOS from being an issue. Adding security to the challenger scene games so that player IP's are not tracable, or hosting the games before actually streaming them so that the DDOSers wont know when to do it. Or scheduling a rematch if proof of a DDOS is found.
I dont know much about programming or the details of how DDOSing works but that doesnt dismiss the issue with the challenger series being vulnerable to attacks like these. The LCS is meant to represent the best that NA has, and that integrity is threatened when the Challenger scene can be cheated like this. Imagine if Cloud 9 was DDOSed and never made it into the LCS summer split 2013.
We cant let the challenger series deteriorate into a matchup of whoever can sufficiently hide their IP address. It ruins the quality of the entire NA esports scene.
