You just talk and talk about physical stats like it's the only important thing. Yes it is important but it is just one thing. Enel's haki, smarts(if he wanted to be) and offense can make up for it and you simply downplay it all. Croc has "weak" physical stats as you say but he still managed to fight till the end in the war and no one one shotted him.
I actually think that people like Marco could have 800 mil bounty. I always assumed WB to have 900, Roger 1 bil and the rest of the Yonkou around 850.
And if you think Jinbei would one shot Enel then why would Oda give Enel a higher bounty than him if their gap in strength is that huge? And have you ever think that could Enel one shot Jinbei if he uses advent of thunder on him? Have you ever thought Jinbei would survive?
My bad, I was thinking lower tiers, md tier then top tiers. Enel is on the upper end of the high tier while his offense can be classed as top tier.
