stable ping is all that matters whether its +50 or -50 , but unstable ping is bad , like when you are in a 1v1 and your ping suddenly spikes to 500 its the worst feeling.
Exactly, stable ping is the key. I used to play cs 1.6 at the time when i lived in a really isolated city, so i had stable 80 ping and it worked just fine. Spikes on the other hand, really fucking annoying.
