yeah i had an open mind to many options of how it worked, and i do believe it is a multiplier, it just sad that something being hyped to be on judaras level is barely capable of handling 7 swordsmen. i see gai as higher than jounin level. i really think hes at least kage level even though his rank says jounin. same with kakashi. kakashi is way op and > kage level. same goes for sasuke/naruto and orochimaru, and others. i know they are two different people, but someone that is ranked genin and is able to pull off the 8th gates can't possibly be a weakling base power level.
Well yeah, it's obvious that Gai won't do anything important to Madara. Just buy time for Naruto, like Krillin for Goku.
I think "Kage Level" is used loosely.
Tsunade and Danzou (For a short period of time) are no where near Hashirama's power.
