I play on the ps2 and my connection has really never had problems, well not like this until recently. I was in a party tanking and the mob just so happened to have blaze spikes up; whenever the melee hit it (and the spike animation would go off) my entire game would just lock up for a few seconds and it kept doing so until the spikes were dispelled.
It seems kinda random and doesn't happen anywhere else.
