I'm heavily involved in the Smogon Pokemon Metagame and I think a RS metagame would be great. No restriction Pokemon matches are full off sleep abuse and Ubers. No restriction RS matches are full of prayer teleporting pjing and general annoyance. Add the standard clauses to Pokemon (Sleep, Freeze, Species, Tiers, ect) and you get a diverse metagame with various techniques and strategies. I'd love to see a RS metagame where not only are cheap strategies banned, but things like DDSs and Whips are banned to. I think we'd see alot more diversity with more rules enforced.
