Have a game mode with head to head arranged wars in a tournament format. Each match lasts a fixed time, highest nw wins.

After each match, everyone resets to the same size, and there's a fixed prep time before the next match. The next opponent could be hidden or revealed before the match actually starts.

Most importantly, the action should be somehow accessible to the broad community, so that people can spectate/commentate/l2p.

Clearly this wouldn't happen in WoL, it destroys the grand melee concept to have all this resetting. It would be a way to add spectacle and give the community something to do other than grouse at each other.
