[Destiny]: Whitelisted dungeon masters.

[Burrito Justice]

Thinking up stories is difficult

Some dungeon masters would just throw a bunch of antags into the mix and call it a day without really thinking up much in the way of a story

Going along with the idea that the DM is selected as a job, if people can't think up a story then they shouldn't select the job. DMs should make a story way before the round and give it thought instead of thinking one up during round start and hoping the crew can expound on it..
As for throwing antags in and doing nothing else, then the DM probably shouldn't be a DM since they didn't bother conjuring a story.
I'm not saying none of this will happen, I just think that all this will hopefully be covered in the DM application.
