Yeah I’m not saying Kata isn’t going to be incapable of hurting Queen, but there’s no way you think Mogura is doing major damage when Queen didn’t even need to block or guard against slashes that cut through steel and stone towers of onigashima like butter and still took no damage there…
And tell me, how are Katas work around on Queen going to work when Queens fighting style involves just taking the hits because as an ancient zoan he’s highly durable and has strong healing. In the end Kata is more skilled, but that skill isn’t going to gulf the difference in power. Luffy was a literal bouncing ball full of air, light and easy to move around. Queen is a multi ton metal dinosaur… I don’t get why you think Kata can move Queen around as easy as he did Luffy.
And again… Gear 3 is fodder. Luffy used Elephant Gun on Wadatsumi before wadatsumi took any pills and it barely even did damage.
