I have no idea who these minions are supposed to represent other than characters from some old FF game. I have no idea why it's important that they are always together.

Seems to me like only those who are dedicated franchise fans would care, and as dedicated franchise fans they're likely already playing FFXIV. Anyone who cares about having both minions has up until the day before early access starts to pre-order.

I don't think anyone who cares is going to miss out.

The amusing irony is that for all people are complaining they don't come together, as minions they will be eternally apart. You can only summon one at a time.
