Are you retarded? How does Zaraki have more battle experience than Kyoraku? Kyoraku is
ALOT Older than Zaraki. He and Ukitake are almost as old as Unohana. There's no way in hell that Zaraki is a better swordsman than Kyoraku. Zaraki isn't holding back alot Jesus Christ. You fanboys make it seem that once he takes of his eye patch, it's all over. So wait, are you trying to say that the current Zaraki could Solo Hogyoku Aizen? Are you saying he's above Dangai Ichigo? Stronger than Yamamoto's Zankai No Tachi? Do you actually think that Zaraki even stands a chance against Juha now that he has Gremmy and James's raw power back? I think not.
You're also forgetting one more think. If Zaraki was so dangerous, then wouldn't he be #1 on the special war potentials list? But why is it Ichigo? Because Ichigo is simply light years ahead of Zaraki, their levels are much different now. I'm pretty confident that Byakuya is a lot stronger than Zaraki as well after he received his royal guard training. As i KEEP SAYING and i really hate repeating myself, AS OF RIGHT NOW, KYORAKU > ZARAKI. In the near Future, Zaraki might be able to surpass him if he ever attains Bankai. Stop being so blind and open your eyes. Kenpachi isn't the strongest swordsman, just accept it. And as for the Kido part, do you think Kenpachi will easily break through Kyoraku's Kido (Though to be honest i've never seen him use Kido). I'm not saying Kenpachi is dumb, but he's not very bright either.
All he knows is how to fight.. Nothing more and nothing less. And lastly, If Kenpachi is so strong, then why didn't the Soul King Acknowledge him and request that he train in the Royal Palace? Why did the Soul King choose Ichigo, Byakuya, Renji and Rukia? Because he all saw that they have tremendous potential to be much stronger than they already are.. Especially Ichigo who at that time was using only about a quarter of his actual Shinigami powers. Stop making Kenpachi seem like some freaking God because he's not. As i stated before in my previous posts, he too has limits. And i know this has nothing to do with any of this but imma say it anyway. No matter how strong you think Zaraki is, he still gets One shotted by Goku hehehe
