Azure is quite bad against 9tails... even if it's not a big problem after 2.0 rework.

My general lineup for 9tails was Azure, Guy (for lifesteal), Hashirama (for barrier) and GNW1010 (for crits and damage). Unfortunately, you can't use it atm.

Just a few suggestions to see a good increase in the dmg done:

1) Use ninja with elemental damage, even on standards.
2) If you don't have the stats to survive the first tailed beast bomb, it's better to use ninjas with stat enhancement (like iruka or playboy sasuke)
3) Try to unlock MB on level 60. He has the highest damage against 9 tails, followed closely by SB.
4) Don't use skills with poison/ignite/tag. 9Tails can't be cc'ed and is immune to debuffs.

What did AF got after 2.0 so significative besides a 200k damage 10 combo chase? Yes, she went from definitely the worst to maybe the worst like BD. The simple fact that you need Guy (who has no elemental damage nor great team wide buffs) to heal up the tailed beast bomb is like wasting 1 ninja in your lineup.

Care to tell me how do you fight the whole 10 rounds with this team? Even if you use AF's heal you can't survive the second tailed beast bomb... or i can't do it at 62k power.
How much BP have you?

the point is not wasting 3 coupons to revive, or to do it the least time possible. Retreating after 3 rounds means that you will spend more time waiting the revive than fighting. Also, the main reason why hashirama is so good... is that you can recast his barrier. In a common WB Asuma, MB, GNW1010 and hashirama you will have only 2 time limited buffs, hashirama's 30% nin and 1010's 15% crit. Hashirama's barrier (40% atk/nin), WB asuma buff (30% atk/nin), MB's ambu squad (25 atk) and bloodthirsty (+1 standard) will last the whole 10 rounds.
