I've been in realms that allowed multiple positions, and I've been in realms that did not. And I'm pretty damn confident that the ones that keep to a one position per family rule do better in the long run. Yeah, it might hurt sometimes in the short-term, I've seen it happen. But I've been pretty draconian about enforcing that rule in Arcaea, and I've had a number of people tell me they came and joined specifically because of that rule, and I'm sure others did that didn't tell me.
i heard from many that arcarea is funny realm, and if you have such rule, people probably willingly accept to take a little more in-game effort to achieve what they would otherwise achieve with additional family member, which undoubtedly provides much funnier game.
