It may actually be better to have each person play a pair. What if one person in a pair can't continue? That leaves a Meister without a Weapon, or vice versa, and that creates a bunch of OOC hassle assuming the character ever gets a subsitute or, in the less likely scenario, someone is willing to use an already-created character. There's just far less OOC hassle involved with each person playing a full pair (or trio, such as Death the Kid having two Weapons).
