I believe it would need to go into extreme lengths before the move must be taken into consideration. Smogon Tiering Policy priorities Pokemon bans first as it is the simplest form of tiering, but abilities (such as Unburden in our case) can get banned if far too many abusers exist (Grafaiai, Hitmonlee, Sceptile, Drifblim in order of viability)With oricorio being qb and venomoth looking like a real worthy suspect next how many pokemon with qd would we ban before taking action on the move? just curious i dont think there should be action on it
If too many Pokemon end up getting banned, the next likely tiering action would be the Terrain Seeds* (Grassy/Electric Seed specifically for providing a defense boost for the Quiver Dance users among other sweepers) before tiering action such as banning moves can take place. Furthermore, Pokemon such as Masquerain and Vivillon aren't considered unhealthy presences as stand alone threats, so I don't believe a Quiver Dance ban will happen any time soon in ZU
*Do note I am not the one electing tiering decisions, take this information with a grain of salt
