I think I'm not making myself clear. So Krieg shows up and, gets fed by Sanji but then decides to be a pirate and tries to take the Baratie, and we get all the build-up to Mihawk destroying Kriegs fleet by Krieg himself, instead of Gin. Then Mihawk shows up potentially takes Krieg down for the gang and then has the battle with Zoro before he leaves.
Then next episode, Krieg has already been defeated. The gang are all still at Baratie and trying to convince Sanji to join but he won't, and we get the Zeff flashback to explain why. Then the Arlong Pirates show up looking for Nami. Luffy and Sanji vs. The Arlong Pirates is the 'hard-fought' battle by they get beaten and ake Nami back with them (maybe she goes back in exchange for Arlong sparing Luffy and co). We then get the crew deciding to chase after Nami in the Merry, which they still have rather than Nami taking it, and Sanji gets his whole leaving sequence where Zeff and the chefs try to chase him out.
So Krieg is here as an initial threat, but he's dealt with either by Mihawk or before Mihawk arrives, making the Mihawk vs. Zoro fight the main focus until Arlong shows up. Something like that is what I meant.
