I can understand if you come against a build that is going to roll you in 30 seconds (mainly mine

Anet give us faction for VICTORIES no matter how its obtained. Its pretty crappy that I have to load the town back up, wait at least 30 seconds for another game, 30 seconds to start the battle, and the foes leave. I get 80 faction for waiting 2 minutes.
Any other arena in GW gives Victory faction even if your foes leave. Why is hero battles any different?
