I don't like these portrayal but I can see what Oda is doing here.
Jabra is not even here and Kaku did a amazing jump in power, while pre ts he was portrayal alongside with Jabra, however after the timeskip his portrayal/equal is clearly Lucci.
Pre ts the gap might be large but current Lucci and Kaku are very close in power.
And Oda don't hold back to also portrayal Zoro alongside with Luffy, both still hold back and didn't used adv CoC. Zoro wouldn't need a extrem high diff against King anymore, mid diff max.
