Poor excuse. Being a crybaby has no implication on his guard point being able to take no damage from Big Mom's slap.
What was the purpose of Robin's actions? It was to save Zoro. Did she succeed? No. Why didn't she succeed? Because she wasn't strong. Who managed to save Zoro ? Rayleigh.
Huh? He wanted to stop DD from chasing the sunny and he would've failed at doing that if Law hadn't saved him. It is quite clear cut. Remove Law and what happens? Sanji would be defeated, Nami and co would've been caught. Which part of that is there no powerlevels?
Blackmailed them with what? Big Mom's vivre card.
Zoro said it in TB and when he begged Mihawk to train him supports it more.
They wanted to be stronger for Luffy but non to be strong enough to protect Luffy.
Exactly and what did Usopp do afterwards? He runaway
What excuse?
Chopper has proven to be a crybaby and coward but when he saw Nami in danger, he forsaken himself to save her.
Meaning a S.H would put their own lives to save the other.
No, you can't remove Law.. also Law told Nami how to keep Doffy at bay by blowing the clouds.
Sanji accomplished his goal at stopping Doffy from chasing the strawhats.
Robin case has nothing to do with powerlevels.
Did Robin save Zoro the first time? Yes
Did Robin confront Kizaru? No
Robin only failed to save Zoro again because Kizaru stomp him to the ground, preventing her from moving him.
Yes, the Vivi card which the homies feared.
So nothing, Zoro did not say anything on what you are implying. He wanted to be stronger for Luffy/ S.h but also enough to defeat hawkeye.
