Well - it was a filler to begin with.
And they might not have jumped the gates, but went through them rapidly.
Why would Guy bother in the battle against Kisame to go through all gates then instead of rapidly activating them?
I have already thought of the idea of a "combat activation" sequence for the Gates.
"Kaimon - Kyuumon - Seimon - Kai" which activates the first threeGates in rapid sequence. However, there has to be some kind of drawback, which I am sure of there is.
However, Hachimon is quite strong currently, so I can't just add another Level to it and grant a combat release, but I have this in mind.
