Occupy towns / Battle for Dalaran
I realize that Warmane doesn't have interest in custom content, but hear me out. I think it would be a nice feature to add a new event. I was thinking it would be at most twice a year, so that it didn't disrupt gameplay too much. It would involve the Horde and Alliance vying for control over Dalaran or another major city. It would involve taking certain points, killing guards, and defending enemy attacks. It wouldn't last long, and there would be no punishment for failure. I would think an incentive would need to be put in place for the winning faction, maybe access to an area or a bit of gold/coins for those who participated and helped their faction win.
I've been mulling over this and I think it would be a fun PvP event for any of the servers.
