Pretty much I think I've only ever seen people use these skills in the FM to try and close my shops. I don't think there are legitimate uses for them there.
I support banning them in rooms (and I think I did lose a mule shop to a genesis spammer once), but let us have fun with them in the entrance!
Yeah I suppose only the rooms are relevant for this issue. Makes more sense to learn in the maps you will actually be leeching in, no?
