If someone is quitting out at the beginning, then the time saved is worth more than the completion points lost by the one player, assuming both players will play another match using that time instead of just stopping. More points are being generated per minute by quick forfeits than by playing full matches. Not saying I’m condoning farming but logically it’s true. If they’re leaving at the end of a match, then yes it is a waste.
If we keep leaving bg matches we will never reach the top Realm milestone. (Jack’s Battleground Blitz)
