Exactly. I'm not even trying to be cynical here. Admirals will have their mainstay presence during the final war, especially since with Akainu, Fuji and Ryo, you have the M3 matchups clear as day.
The problem is much of this forum has filled this headcanon that Kizaru used a beam saber once against Rayleigh, it automatically means its a Zoro fight. Then, because he'd be the strongest enemy here on Egghead, it automatically means he can't be defeated by anyone here lol, especially not Luffy whom Kizaru has had more encounters with on a personal level during Marineford.
Just funny how the collective mindset thinks here, you can see it coming from miles away.
