How often you get "unrelated" laggs when pvp starts?

Few times had a chance of pvp here, some of them were lets say "interesting'. Just b4 other guys charge at you you get huge lag spikes ^^ You can mostly predict having these lags actually, if someone you are about to fight has a nick that has some meaning in ru and he is not way way better geared than you you have a good chance of getting that "skill" based pvp ^^

Just wonder how many have had this experience
