naah,just like whitebeard's 32 pirate allied crews they will be called when needed,that's all.
This. Dunno why so many people think they will hangout in Thousand Sunny. Just imagine when Luffy goes to Marineford again with these allies backing him up. I'm sure these aren't the only allies either and Luffy will have more people following him around just like Mihawk said he has the ability to turn almost anyone into his ally
