I mean, wasn’t Kizaru literally implied to be able to destroy the crew in a 1v10. A conflicted, non-serious Kizaru did outlast G5 and even helped Luffy. A conflicted Kizaru one shotted Luffy’s left hand with a no-name kick. Luffy’s right hand man could not even properly finish off a low ranked lackey of Celestial Dragons. Gunko negged Jinbei, Brook, Nami and Usopp.
Oda clearly showed Luffy, Law and Kid are absolutely not ready for the final stage. The best course of action would be SHs losing in Elbaph, Luffy losing his Yonko status, WG taking hold of Sunny and their RPs.
Luffy is strong in G5 but his time limit issue is an extremely serious handicap. Zoro cannot keep relying on sigma male energy. Whoever taught Sanji haki should put a bullet to their head. Jinbei falls short in terms of strength compared to most of the warlords. Rest of the crew cannot even use Haki.
