I'm a reader of those slaves interations and found them refreshing.
They are fun tor ead and the people that participate in them being the Pokemons AU or the Slaves AU. They are pretty investes in them and i like that.

There was just oen that i read where the separate RP took part ont he main prompt post and it was really long. Then someone started to prompt them separately and that was an even better idea cause it was only for that purpose.

I dont think a differen community is necessary, only post them in different prompts and they can have all the fun they want
