The rules are mentioned in the rulebook.
Third-party organizer, their rules. If you did not speak up during PRX vs Exploit then just accept the same now + I did not see noxxy tweeting out when other teams were facing the same issues. I hardly saw anyone from Exploit have issues with it either.
AE was not even invited. They decided to register for the tournament and play in the open qualifiers. It's not as if anybody forced them to play. PRX decided not to play for example.
Also its kinda fair? It's not as if AE is out of the tournament so by probability they will still get a lot of games with SG server.
TEC is an Indian TO, why should SA teams always play at ping disadvantage? RNT was at a disadvantage against Fancy. If the server on GE vs Bleed is SG, GE will be at a similar disadvantage.
Also ping is an issue that cannot be resolved but packet loss is your issue and has nothing to do with distance and server placement. It just means you have shitty internet.
Riot is to blame for so scarce server placement in Asia. They cannot give countries their own server but put like a server for every state in the US.
