I never liked Ace's bounty to be honest. 550mil is just way too low for a commander in a crew like Whitebeards. I think there are going to be a lot of bounties like the commanders that Oda will just leave to the imagination, or show as a wanted poster in the background of sme scene.

As for backup, I don't think it's Oda's going to ship in old characters from across the New World in the middle of the arc. If anyone's going to help Luffy, it's going to be someone who is already involved in what's happening
