So it's been a while since i used fire main (been using water main after the tobi nerf)

I'm now wondering who is the best 9tails team with fire main, i know that fire main, iruka, asuma wb is one of the best,
I have some question about the barrier caster,

Hashirama is the best but not everyone has him.
Anko
++get fire buff from fire main, iruka, and asuma wb,
-- she doesnt buff asuma wb

Onoki
++ buff everyone in the team, elemental std attack, gives extra std attack
-- BACK PAIN, doesnt get buff from iruka/fire main/ 2nd round losing hp so no buff from asuma WB

Danzo
++ get fire buff from fire main, iruka, and asuma wb
-- his std attack deal low damage and no elemental bonus

Mei
++ you can play manually,,high damage std attack+extra poison damage
-- doesnt get buff from iruka/fire main/ 2nd round losing hp so no buff from asuma WB


Who do you think the best barrier caster for fire main here?
