Seems like you didn't get my point.
You are doing vast injustice to any character who has actual feats of strength/power in a actual fight by taking your example of fodder executing Roger into account when discussing actual powerlevels.
There is instances where Oda disregards how strong a character actually is for story/plot and Roger being executed is being one of those instances as well as Shanks losing his arm and Oden dying by a gunshot that was also set up as an execution. (Also in Oden's case like i mentioned before he was already severely weakened when Kaido shot him)
It'd be completely unfair to Akainu or WB to disregard the feats they have portrayed during a war as just a plot device whereas all previous mentioned instances were actual plot devices.
I never argued that piercing WBs durability is the best feat in the series did you even read all of my prior comments?
WB tanked every attack even Squardos. Tanking means you take an attack that either damages you or doesn't damage you but you still keep going regardless. Tankiness is connected to both durability and endurance. Kaido is a tank due to his durability but as soon as someone bypasses that durability his endurance falters, from the feats we have seen so far that is, when just one of Oden's attacks KOed him temporarily. Whitebeard has bad durability but he has the best endurance by far by feats. And from what we saw in MF no character in the series can overcome WBs endurance with only one hit except Akainu.
Also btw
@Cinera @Finalbeta you guys resigned or smth? Since you haven't answered my last arguments at all.
