Literally what are shanks feats that could put him above ray?
Shanks in prime; blocked an admirals elemental attack with ease
Rayleigh out of prime (~70 years old); blocked an admirals elemental attack with ease
Shanks in prime; barely gets attacked my marines BC they aren't allowed to attack Yankers
Rayleigh at 70; never gets attacked by marines BC he is that fucking guy, he is a lone entity and marines can attack him openly. (Oda counteracts this by pretending marines didn't know where he was through kizaru's words but that's a load of fucking shit!!! Mfs got the best information network maybe only being beaten out by big mom and big news)
Shanks in prime; railed Kidd, a 3b bountied wind bag.
Rayleigh at 70; had BB shitting the fucking bed, whilst having backup. Rayleigh was even doubting himself but BB was having a mental fucking tizzy at the mere sight of this big dicked mother fucker.
