@BurnSchulz. That theory made me think of Killer bee from naruto. The guy uses 8 swords to fight and he owns with it.
But that makes me think. Luffy's upgrades are potentially endless (excluding haki cause their fighting styles wont be effected). Luffy can add more gears and the fact that he can
possibly get a weapon to use which would grant him two ways of fighting. But then there is zoro and with the exclusion of haki, what real upgrades is he going to get that would allow us to see something new. Getting different swords still aint going to change the way he fights. Mihawk training him is indeed going to make him stronger, faster, but subsequently what we would see is him fighting the same only that we know this time he is stronger and faster. Thats what i dislike about Zoros fighting, that from what we have seen, at the level he has grown to in swords fighting, he pretty much fights exactly the same as someone below him......except we know that he is stronger. The zoro vs kaku fight is a good example. In that whole fight, the most versatile was kaku and his sword fighting was much more impressive than Zoros (because of his devil fruit). Zoro just fought exactly the same as he always does then did the one second Asura. The way i see Zoro's sword swordsmanship progressing is basically stronger ones of those one second techniques he does whilst the rest of his fighting would remain boring (on his part). I hope Oda makes Zoro's swordsmanship more versatile like kaku's. Even if it means giving him a devil fruit, and that is not me inviting a discussion about him getting a devil fruit or not cause it remains a fact that it's possible.
And im aware zoros techniques aint literally one second. I only tried to express the way his sword fighting is basic when fighting offensively and is not really effective against his opponents until he does one of his techniques which actually is like one second if you dont count the build up. It would be cool if in the future Zoro's sword fighting would allow him to have fights like luffys where he is actually doing major damage to his opponents in the course of the whole fight rather than having a technique that just finishes everything.
And also, on the discussion about who is most likely to become fleet admiral. Its simple, aoikiji is more suitable but akainu is most likely. The discussion came up in
this thread and
this is my explanation.
