It's about the potential that technique has in Zoro hands, he will be far more deadly than Kinemon using it how can we not be excited
Well yeah, it's another great powerup that Oda just gave Zoro, that is going to be extremely beneficial to him in the long run. However, at the end of the day, it's another recent powerup just like Enma was, that some of these Zoro fans are using to act like Zoro was Top Tier out of the timeskip. That doesn't even make any sense.
Zoro has now been given two powerups in order for him to be standing on the rooftop alongside the other Worst Gen members. This notion that "he was just that strong" out of the timeskip has been debunked.
