Agreed. It's something I'd love to try.
For the really hardcore people, I'd also like the option to immediately end a TF if the Master Of condition was failed. So not only does the team not get the badge, they don't get the merits either. This is something that I feel would need to purely optional and something each member would have to click to agree to. Hell, a team that takes that gamble could even get more merits than a typical run, maybe double. Would make things really interesting when something is the weekly task force.
