I am sure that if GenG underperform and go out early or a chinese team goes on a run and wins Shanghai dumb vlr users and redditers will endlessly call Shanghai rigged, even if the results are completely legitimate.
even actual sports are very difficult to rig, but its rare for val fans to listen to common sense... would need to be very blatant to rig like constant convenient tech pauses when EDG are losing, every non CN team getting horrible living amenities, some bullshit with players getting worse pc's, even then it would not be a garauntee with how good the field is.)
