One Piece Chapter 511

[Splash!]

Nothings bad about it. However, what makes you think that Roger, Whitebeard and Shanks knew it? Because they had to go to the NW and pass by Kizaru, Akainu or Aokiji? If that is your argument then I don't think you have much a base for you backing. They had huge crews much much much bigger than Luffy's crew. Even when they were young building their crews up. Granted, if you say that they knew how to beat a logia user, and there were people in their crews strong enough to learn as well, then ok I'll accept that.

I am confused. Are you saying that pirates of 'ye olde times' knew of ways to beat typical logia users but that doesn't translate into beating someone of an admiral level? because I don't think anyone is disagreeing with you there.

What do you mean you just leveled up every logia user in the series? I don't understand quite what you meant by that.

I think what Death Boo Z means is that any logia users we see from now on in the New World will most likely know of more advanced ways to utilize their devil fruit abilities because the possibility of being harmed physically calls for better methods of offense/defense.
