Basically, this is a GM’s first campaign, and there’s a lot of stuff she’s doing that’s against “GM best practices” and that I can tell are annoying other players as well as me.
So, do I bring this up to her? If so, how do I do it that doesn’t make me seem like a jerk trying to usurp control from a first-time GM? I want to be supportive, but I am seeing her make rookie GM mistakes. Do I try to push back to have a better time in the game - or do I value the necessity of her making these mistakes?
Did she ask for your help?
Did she complain that folks aren't having a good time, and she doesn't know why?
If not, it would be showing her great disrespect to step in.
