In scenes with the former (the 'do all the things'), I end up just not... doing much of anything at all because I get tired of not even having the opportunity. There are people who just sort of need to be led by the hand, but then there's also those who give up because they realize that their poses are just going to be fluff and filler because Sue over there is jumping pose order, is complaining OOC or on channel whenever someone else does something, and the ST involved says nothing.
I've tried paging the ST before in these cases. To say 'Hey, I appreciate that you're running this... But because Sue keeps jumping pose order to do everything, no one else even has a chance. I haven't even had anything to pose except reactions to her and I'm starting to flag.'
Maybe we should encourage more players to be brave enough to speak up?
As an ST, one thing I've done to help spread the love, as it were... When I, say, ask for a Perception roll... I give everyone a different bit of information (if possible; sometimes it's not doable). That way, no matter who is posing or in what order, everyone has something to contribute. I also page them all separately... as I've had an ST page everyone who succeeded to say "OK, Auspice, you see Y and Bill, you see Z." and Bill poses seeing Y and Z.
There's a lot of psychology to it, sometimes. And you just have to learn that a larger number of players than you'd like need to be treated like children. You can't tell George to share the candy with his brothers and then just turn your back and expect him to do so. You've got to hand it to them each separately as George is probably going to run off, eat it all, and tell his brothers 'Oh, it was only given to me.'
Do you treat everyone that way? Hell no. But it's why 90% of what I run on nWoD is for my friends and 10% is for all comers. Because I can only handle the stress of people management on top of STing for so long.
