Yeah i agree with you there. that's why i think White Beard and Shanks (and probably also Hawk Eyes because i think he's purely swordsman like Zoro) are at the top without any powers and i also think White Beard could and perhaps have beaten Ace which might be the reason he follows him now. Question is just if he joined White Beard before or after he got his DF.

But like i said. If Enel fought more wisely he would be unbeatable. How can anyone defend against someone that doesn't even need to be anywhere near you you attack you?

Unless Enels powers only where that strong in Skypeia. He could hear everything that was said or done all over Skypeia and he could use his powers to strike anywhere to punish anyone he thought deserved it. And if he has the same range down on the ground as he did in the sky he can sit on a boat in the harbor and strike anyone on the island he is docked too. No one except the people that has immunity to his powers can stand up to him. And even then he can just keep his distance. That way even if he can't beat them, they can't beat him. Also i don't see many powers that would even be able to affect him even if they got close to fight him.

Also i wonder how people that only have fighting technique would be able to attack someone that can't be attacked by physical attacks. Like Black Beard said to Ace after punching him. "It must been a long time since someone hit you" or something along those lines.

Anyways if Enel just used his power in a smarter way (yes it might be a cowardly way to fight) he can't be beaten and there wouldn't be many that could even stand up or survive his attacks. Unless the likes of White Beard and Shanks are considered so strong that Enels lightning beams from the sky would be considered no more then a insect bite. Which to me seems to make them way to powerful.
