Like I said to you on teamspeak, you can see your ping in spec so why would you join in the 1st round and then go back to spec within seconds?
Saying you have a bad ping (which is visible in spec) just sounds too much of a coincidence.
You were playing the last map fine and of course ping spikes can happen at any time but like I said - too much of a coincidence and they way you were talking in teamspeak didnt do you any favours mate.
When I have ping spikes I wait for a while to see if it dies down - im sure other people might do the same thing too, no?
