Lmao what delusion. Roger and WB cracked the skies while these two cracked their bones. As per your asscannon Lucci has advCoC too.
Nah not the same thing, Garp and Kuzan had the same streaks as the Roger and WB clash, those are missing here completely and I don't think have ever been drawn for a single CoA exchange.
Two differences between Garp/Kuzan and Roger/WB panels.
1. We don't see anything emitting from their fists
2.They made contact
#2 is not an issue, as you can make contact with ACoC, and also Garp would probably want to make contact with his fist, it would probably take away from the hardness of his blow if his fists aren't making contact. #1 seems to be the outlier compared to other CoC instances atm.
