One GP may perceive 200ms as "too much" lag, another GP may see 500ms as too much
One GP may not be smart enough to differentiate connection issues and warping from delay (something that every foreign player experiences), etc.
All of this enables GPs to hand out "my best guess" bans, and that's awful. There needs to be some hard limit, or a cap, or some concrete instruction on when it is or isn't correct to ban someone for lagging.
Until then, bans like this are going to be extremely inconsistent and applied unfairly to the better sparrers. We actually have dedicated groups who organize against players to spam report them and increase the chance that they're banned now? 100% ******ed...
Yet as we speak, we have this dude VPNing in side rooms to significantly increase his ping against new players who have no idea how to spar against it:
My report doesn't count though, because this dude is irrelevant and no one cares about him. Can I get a group of 20 people with me to report him so something can maybe get done?
