Guild Wars 2

Was in an sPvP match, switched teams for autobalance, the team I switched to lost (make of that what you will :p ), but I still got credit for my “monthly wins” achievement. Is it a bug because of the autobalance team switching or is it intentional?

intended. people complained about autobalance taking away win points.

Always been this way. If you get switched or volunteer it counts as a win.
