You are free to believe what you want, but panel time is not an indicator.
Look at what happened in Marineford, Teach and his crew arrived in chapter 575 and left in chapter 580.
5 chapters in total, not even centred on them (except 1 or 2) but at the end of the day:
- Officially killed Whitebeard
- Stole the Gura Gura
- Fought briefly with Sengoku
This is just an example to show you that doesn't matter the
quantity of panel time, but the
quality.
Also giving a look at the ranking you posted, if we are supposed to take it as the relevance of what the character will do then we should take for granted that Raizo is more relevant than Linlin or Kinemon more than Oden. Doesn't make much sense.
All this panel time thing is a narrative technique of the author, absence keeps the reader wondering on what that character is doing/will do. And we all know that Oda is a master of this kind of shit.
I'll not try to persuade you that Kidd will kill Kaido, I have my reason to believe it just like you have your reason to believe Zoro will do it, what I'm really trying to say is that most of you are judging Kidd character from the wrong perspective (and a lot of bias), often going against what Oda literally draws.
Let's be clear on this: a lot of you wank Zoro to much
