I cannot stress enough how frustrating it is playing against a whole team of players who are all pinging 300ms+, when I am playing at 50 ms ping. It is not fun trying to shoot players who teleport all over the map!
I am playing in the Oceanic server region, and to be honest, there are more players with ridiculously high latency, than players like me who are local. To give you an idea, a typical Oceanic Australian server I join has at least 12/16 players with 200/300+ ping! I have never in my life even tried to play a game at such ridiculous latency, and if I happen to be one of the 'laggers', I simply leave out of respect.
This is ruining the MP experience for local players!
