The wording is making it hard to understand.
WB was decisively stronger than an emperor and same goes for his crew. An emperor typically has 3 commanders and WB had 6 to 7, one of them being a top tier(Oden). Over the years, the WBP got nerfed to the level of a standard yonkp crew and they got crushed by the Marines.
-the admrials could go all out
-WBP got reinforcements
-3 of the warlords helped the WBP
-Not all the Marines were present in MF as they were still scattered through out the world
-Garp and Sengoku mostly watched
-Only notable losses for the Marines were John Giant and Lonz.
Individual power levels hardly matter. Marines were the much stronger force. Even Kaido, despite having the much stronger army, was afraid of BM starting a war with her small group on his territory.
As I told I'm from germany and grammar is not my strong point
WB was not he was equal to them no Yonko is significantly stronger than the other there is a gap but not that big
And whats more MF WB was far from yonko level
he couldnt even properly use COO while in Wano he sensed Oden miles far also he didnt use advanced haki to stab Kuzan if he would then even if Kuzan would create a hole the invisible armour would hit Kuzan haki wise he was down to minumum level
physically he was in bad condition despite that he held his own against the marines
So MF-WB just shows how big a gap exist between a healthy yonko and a admiral
This didnt go all out argument is also true for Marco who didnt go hybird mode also for Vista and WB didnt also go all out or couldnt go all out
for the crew dynamic
WB lost Oden his VC-level fighter and WB nerfed himself the grew gathered more followeres the quality did go down by losing Oden and Thatch
Also the decreasing health of WB
At all BMP and BP seem to be stronger
BMP are far bigger
BP are in a competition with each other
for the top three WB had
Oden, Marco and Vista
WB got reinforcement but the marines got the pacifista whic turned the tide of the battle for 1 hour and half the battle was equally fought until the pacifista appeared
Yes the marines are a greater force but they gathered there most elite soldier from all over the world together so WB fought the core elite troops of the marines
Yes they did because WB was on death doors the assassination did a good work
Of course youre right the marines are a greater force but the equation 1 Yonko= 1 Admiral cant be true otherwise
In fact its 1YC= 1 Admiral
