User blog comment:Plainblack/Trouble In Paradise? The Strawhats Are Too Weak!/@comment-130.102.158.16-20121119051032

Rather than actually having the core crew members branching out into armadas, I think it's probably more likely for the core crew to remain on Sunny as their flag ship, but having other smaller pirate crews get impressed with Luffy and joining under his flag instead. That's probably better than having the core members 'lead' different crews because that'll just wreak up the whole bond they have.

I'd think some of the rookies that just entered the new world after being freed from fishmen island, if they haven't all been caught by G5 (were they ALL caught?) should end up joining under the straw hat banner.
