This trick works for everyone, and I do mean everyone. It works in EVERY game as well!
It will lower your latency no matter what unless you have a real connection problem, like 5000ms ping... At which point it may give you 4300ms ping.
When I tested it, I dropped from 140ms ping, to now 43ms avg. woot! =)
No it's not rick rolled you ding bags.
