This needs to be stopped, and immediately.

You're a tad wrong there. If the roulette didn't exist new players would have to wait a VERY long time for the queue of their mandatory story duties. In my opinion, it's only polite that said new players move at the pace the other 7 are moving, and watch the cutscenes in their room when they're done.

^ This logic is boggling.

If the new player doesn't care about CS, so be it. If the new player, like the OP, is interested in the CSes, then the "courteous" thing would be for players to actually wait and be supportive. You don't ask newcomers to immediately get on your level from the get go. It should never be expected.

If you're in a hurry, Praetorium is the last dungeon in Eorzea that requires speed running. You can save yourself the grief of trying to do so.

Honestly. There are better and much more efficient ways.
