Since (at least on my server) we aren’t being given the choice on what faction to join (since ones full), both sides of the assault event should be getting a reward, win or lose as long as you participate. Not doing this is also forcing people to goto one faction over the other (red in our case) because otherwise your wasting 45 mins on assault days for no reward.
This isn’t even going into the World Boss kill, which has it’s own whole set of issues.
