Imu literally saw Luffy in front of him. What are you talking about? How is that a sneak attack? Base Luffy is even yelling at Imu. Is Imu deaf? Are you desperate?
So Imu is not looking at Zoro but Zoro still failed to blitz Imu while Imu is looking straight at Luffy but Luffy managed to blitz Imu.
Show me panels where it says Katakuri uses Future Sight 24/7.
Show me panels where it says after Katakuri was hit by hallucinogen gas, Katakuri can still use Future Sight
Again dude all it does is hype Oven

It doesn't dehype Katakuri since Katakuri has a track record of blitzing Gear 2 who is much faster than base Luffy who is much faster than KOH Zoro.
So either Oven is much faster than KOH Zoro if you're adamant that Katakuri's using Future Sight or
there's no proof that Katakuri's even using Future Sight at all.
Either path you choose is a terrible downplay for Zoro.
