I'd buy them as needed, yes... Right off the bat I'd probably only get 2 or 3, but I'm sure I'd work my way up to the max amount eventually.

Muling right now sucks really bad, because there's no mailbox, there's lag on the inventory screen, and well, there's no mailbox... Plus with events that give you like 10 rare/ex swimsuits, yeah... Gonna need a bigger boat ASAP.

I think the max of 2 retainers tending the wards at a time is a good idea though. We don't need it clogged down to bejebus with like 8 retainers per person... It'd be crippling even now, but just imagine after the game relaunches and gets a bunch more people playing. It'd just be stupid. It's already over crowded with 2 retainers per person and a limited total population.

Anyway yeah, I'd buy more retainers in a heartbeat.
