Okay, I thought it sounded pretty neat. When the patch came out, my wife and I ran into the Deeprun Tram hoping to find some alternative content to pass some time. We looked around and saw some brawls going on but no way to get invited to the guild. We asked in our guild how to get in and were told you have to get lucky and get a drop from the opposite faction NPC's and what not.
So, we left and pretty much forgot all about it. If there would have been a quest chain that would have guided us along we might have stayed interested. But to go grind for some drop just to queue up and wait to do some solo fights for some meager rewards, we didn't really see the value. Perhaps this was meant to be a spectator thing as much as anything.
Did we miss something? Is there more to this than met our eye? For now, when I log on, I'd rather be doing some battlegrounds, quests, or dungeons and filling in idle time with a pet battle here and there.
