Guild Wars 2

I was on a streak and i draw a match does it count as a defeat or a Victory ?

your pips are unchanged

But do i lose my streak? i lost the next game so i can not tell.

Judging on the reward/rank points it was most likely a defeat. If both teams end up with the same score, the team with higher total personal scores will win.

(Not sure what happens on a real draw though)
