[quote=@Grimhildr]it'd get rid of useless clutter (no offense, but they all get very little activity) and help to remove some divides, maybe even reduce the amount of cliques, since they'll all have the same subforum and be united a little more, i guess.

I do not agree with you that it is useless clutter. RPG already has a simple enough aesthetic structure that works for it, minimizing it more won't really give it any further utility or benefit outside of confusing the users of those sections.
