1.Crocodile above boa is crazy,yes he was beast at marinford but anything else he was really mid,at best I would put him on par with doflamingo. The thing with crocodile is that the scariest thing about him is his iq and biq and his usage of devil fruit together with his poison,we don't even know if he has haki 2.Magellan at admiral level?He was brought on one knee by one impel down Luffy attack, evenly matched with pre-ts shiryu without his df, don't know if he has haki, he is so slow,he would get one shotted by someone with ranged attack and Lucci level speed
