After Wano, Elbaf will likely be the only major arc before the SHs reach Laugh Tale. Given how close the SHs are to becoming the PK crew, all of the SHs really need to have at least basic Haki by the end of this arc. Given that random fodders in Yonko crews, like Opera’s trash brothers, can casually use CoA, it would be embarrassing for the SHs of over half their members either can’t use Haki by the time Luffy becomes PK or just manage to learn it immediately before he becomes PK. The SHs are vastly smaller in size than crews like the BP or BMP, so in order to make it believable that they deserve to be called the best crew, then all of their 10/11 members should have access to at least basic Haki. The only SH who I would find acceptable to not unlock Haki in this arc is Nami since she has never been strong physically and had always almost entirely relied on her Clima Tact, but even then I was still disappointed to see that she didn’t unlock CoO when she beat Ulti. Instead of having Zeus home in on Ulti in order to counter Ulti having good enough reflexes to dodge Nami’s attacks, Oda should have just had Nami learn CoO in her final clash with Ulti so that she could use CoO to counter Ulti’s reflexes and land her hit
