never had 4 people quit at the same time, only once had 2 people. I PVP alot of the time. exaggeration does not help prove your point!!!!!
Then you're lucky. And it might not be 4 all at once... but once 2-3 quit (and I've seen that quite frequently), the imbalance in players usually leads to events which lead to #4 and #5 quitting, etc.
Sometimes it isn't noticeable unless you're watching, because by the time #4 and #5 quit, players have already begun to backfill the first 2-3 spots (even though they aren't in the warzone yet because they're still stuck loading).
I guess I'm just becoming hyper-aware of it now because its happening so often and seriously making me rethink my spending decisions in regards to this game.
