As an enfranchised player this new mode is the least exciting part of the update for me. It seems potentially annoying to be checking in every hour or two, just like Voting Gauntlet. I hope all of the rewards can be grinded without being forced to clear Infernal maps, similar to Tempest Trials. The winning faction getting more rewards (if they aren't just feathers) would also bug me.
That said, that entire broadcast was awesome. 0 Stamina GHB's, better TT, and re-worked summoning pool are super, super amazing.
