You don't want to do savage even with a group of non randoms... oh wait, that's my opinion.

The clear rate in pugs aside, the option is still an option. If people want to do it in DF why should they be stopped from spending their time wiping? They can make their own choices.

Who knows, maybe after the initial rush period most of the bads could give up and eventually make it pugable.

Also people can join DF even with premade groups. Maybe someone is just missing a healer, maybe two light groups could join in etc. It wouldn't be entirely impossible.
