This 100%, it also offloads some some marine designs for the endgame, and there are fuckton.
If Luffy takes out an Admiral and the rest of are VAs of different scalings (consider the difference between Garp and Maynard lol), it also paves the way for Zoro/Sanji to take on Admirals on their end later
My only question is Aokiji, will he receive separate focus from Blackbeard? Its odd that at 11 members, he's one of them and theres no way anyone sans Luffy or Koby would fight him at this point.
