It's also BS when people bitch about pings.
I've played both as and against people with 200 pings on a half dozen modern games (BF2,LOMAC, Homeworld 2 being the major ones) and the code (written well of course) can compensate effortlessly so no-one even notices except in the MOST extreme cases and THEN it's barely able to be observed.
I mean there is nothing I love more then going onto a BF2 server in the US with a ping of 180 and have some kid instantly start screaming "OMG, kick the lager LOL!'.
Thankfuly most of the time the people on the server say that a 180 ping does not lag the server in the slighest and tell him to STFU.
One time a month ago when I was waiting for a friend to join a US server, I was snipping and blowing the heads off this guy and he (clearly beliving himself unable to be snipped when bunny hopping like a fucking moron) see's my ping and starts screaming.
Unfortunatnly for him I had been in the admins squad for the last 10 mins and we had really worked well togethr and he could see I wasn't lagging anyone.
So he just banned the dipshit
Of course on MUCH older games with poorly written netcode like CS, ping can be much more of a problem.
