Yes... because so many people will be jumping on the option to "queue for war zones in progress". I'm sure any disconnects or leavers will get backfilled immediately with all the people jumping at the opportunity to join a Huttball match at the 6 minute mark.
Not trying to be completely rude... but that's a really horrible idea.
I think it only has happened twice that I zoned into a warzone in progress that my team actually was winning. Most disconnects have to be from people living in the outback on a satellite connection or people too chicken to press the leave warzone button. Neither of these players are going to make a difference anyway and you would have won without them. If people leave in droves there is a reason for it. Just let that match end prematurely. But what do I know. I'm a pro-quitter thanks to that inspiring thread a few months ago.
