2 (+backup of hundred of fodders) vs 1 more than make up for the idea that they haven't fully recovered. At no point it is even implied the 1 week injuries were the reason for their fat L, but somehow ancient zoans happen to have the worse recovery rate ever seen in the series, how convenient.
Yet they were pictured with heavy bandages, there was not even an actual fight on panel but just GB piercing and sucking them. I agree ancient zoans should have great recovery but the point was that Oda needed them to somewhat hype GB at least a bit before what happened to him next (also they lost contrary to Luffy&co).
They started fighting in 1054 and they were neutralized in 1055, he wasn't even going for the kill as he was trying to bargain Luffy's head in exchange of him leaving Wano at this point.
GB was not yet serious but the scabbards either were not going all out yet, Yamato as well. If they were in danger Luffy, Zoro etc. would have jumped in the fry.
She literally cheapshotted him at the back of the head with ACOC and he didn't even care about her existence afterward, caring more about the pink dragon. She's an irrelevant ant to him.
She was calmly discussing the course of action while trapped, also she didn't even come remotely close to think to go hybrid.
What? This was said nowhere. If you're going to pretend to know what is in the character head, anyone can do it :
Luffy simply respects people wish to fight their battle, and was ready to intervene as soon as Ryokugyu would go for the kill.
Indeed, they were watching Momo and co fight GB without really caring because they sensed no danger for them (yet).
This is his only really bad showing, but this is no much worse than some of Blackbeard reactions.
Hardly little effort though, Shanks had veins on his forehead and his haki was leaking so much that he was knocking his own crewmates despite the fact a proficient COC user is supposed to be able to chose his targets according to Oda in the SBS of volume 65.
Outside Shanks, all of Ryokugyu downplay is based on headcanons.
What people saw was Shanks wifi haki shock GB from dozens of kilometers away. Ok he knocked out some weak crew members who can not beat his haki, a bit like when he met WB with WB crew, had some veins, ok, but the portrait was clear and GB come out really bad from it. But in the end it is not GB who is really weak ( he did good with Weevil) but Shanks who is strong. Yet this intro, his very intro, turned GB into a meme.
