Garp literally told whey wouldn't took two legend at the same time, putting Ray and WB in the same sentence and in comparison.,
They literally mobilized their entire force for Whitebeard alone, all Admirals, Shichibukai, Sengoku, Garp, most known Vice Admirals etc and still Sengoku said they could lose, of course taking on another legend when they have nothing to spare would be a terrible idea.
Yeah, and that includes Ray being that strong in his prime that his fame alone kept BB to fight against old Ray.
And your guess is as good as mine for how that fight would go, just headcanon at the end of the day.
Could have used WB, or Roger, or Dragon.
None of them were confirmed CoC users at the time and none of them had demonstrated it.
Rayleigh and Shanks had hype moments where they used CoC and are immediately recognizable for it, Shanks when he was on Whitebeard's ship and Rayleigh at the slave auction, it's obvious when you think about things logically instead of solely from a powerscaling perspective.
Yeah, my well known Ray agenda.
Not necessarily a Rayleigh agenda specifically, but more like wanting to reinforce your own faulty personal powerscaling so you interpret things in ways that suits it, and besides, you wank Rayleigh to wank Admirals, it isn't subtle.
