Piñata

The pinata mutator (properly piñata) is a mutator in which a death of a player triggers the player losing not just their current weapon, but all their weapons that they possess. This is a boon for defenders, because they don't have to leave the base to get weapons. In addition, defenders are rewarded by getting weapons that are difficult or risky to get, or come from an area controlled by the enemy. In addition, if there's a shortage of ammo in the map, defenders (who do not roam the map like midfielders or attackers) can get their ammo from particularly stacked attackers.
On the other hand, the opposition claims that it creates too many instances of controlled weapons, that are powerful on the map (like a nex on a flat map). They claim that it creates spam because every player has a strong weapon, which the mapmaker may have intended to be limited to a certain few.
