Except for Luffy's MC factor who reached kilometrical heights this arc, I don't see Kidd writing as bad or something...
The only thing I complain about is how the Kaido-Linlin switch happened, I understand that they had to think quickly but that was rushed.
As for the panel time, Kidd's will be the second last battle showcased in detail so it makes sense that the best is coming later. I also expect next chapter to have a focus on Kidd-Law vs Linlin similar to the one Luffy-Yamato-Momo vs Kaido had this chapter.
In a nutshell, I think it's not about bad writing but about people feeling the urge to belittle Kidd, no matter what he's doing (fighting Top Tiers no stop, for example...)
