Boba as Fleet Commander?

Akbar is a confirmed commander - Boba likely won't be a commander, so their roles are likely going to be different. So, unless you don't have AA, work on him right away, as Boba should be good enough for his role

He might have his own ship, which is likely to be cool, but he's definitely not going to be a commander. He's a solo bounty hunter. He only worked with other bounty hunters as a kid when he was learning the trade.

Commander > other support ships
But Slave I would be one way to help make Boba a better toon

Short answer: no

Long answer: why would you? Do you have mace or GT, they are the only other announced fleet commanders.

It seems that they will have the biggest initial effect on ships much like a good leader on your team.

Maybe! @EA_Jesse released more information about ships, the crew members which pilot their own ships or whatever but bobba fett at the moment is not a designated crew member, but he probably will because the Slave 1 is on the ships table. Meaning they will probably add the Slave1 with bobba fett as a crew member in the future.

Right now they only released 4 toons that have the crew member ability: Biggs Darklighter, Wedge Antilles, Empire TIE pilot, and Ashoka Tano.
