Yeah, but you're comparing Wano, a 4 year arc(as long as some manga lol) where Luffy got like.... 3 powerups? To a fight that's happening right now, that probably ends with either the SHP running away, or Imu being self sabotaged or some shit.
But anyway, you have a right to your opinion obviously. I just can't personally visualize him out preforming Loki at this point, I don't think it's where the story is heading.
