While GI seems relatively unimportant story-wise, it's HEAVILY important on character development.

For the first time, we are able to see just how destructive Gon is willing to be, while on the opposite side, we see a lighter part of Hisoka. You also have Gon and Killua's Nen development. It's a fun little break between the seriousness of Yorknew and the Ant arc.

They won't be skipping it.
