Everything has to be +hp in that team, also azure fang and roshi. Guys, that team is an endurance team that highly suffers from ignition and that highly benefits from stacking up and if the ninjas are dead because don't own enough hp how can they stack?

Giving +nin to azure fang doesn't grant her anything when you are ignited, chaosed or immobilized, while hp grant you the chance to maybe survive the round and heal later and if azure fang dies, and now with the easiness to face cloud blitz teams that can happen a lot, you lose EVERYTHING.

Sailor sakura mood depends on your tactics and on your distribution on the field, If you put her behind roshi there's no point im giving her -atk because repulse damage will nuke her regardless her defense/resistance and once roshi dies she follows instantly even with that +5% defense you chose to not remove from her. Conversely, if the enemy isn't able to nuke her, that +5% attack, with enough stacks, make her damage pretty annoying. Remember that mood decreases the basic attack, is not like 1 less stack.

If your issue is that one you are right in doing so (even if, i don't know you, but I'm currently sitting on over 3000 dangos), but here the question was what was the best mood for the ninjas in that specific team.

Azure fang regenerative healing jutsu benefits from 25% ninjutsu, healing jutsu benefits for 18.1%. If your battles never go over round 6 you are at loss there in comparison with +life in total global benefits even if your main is able to use the standard attack every round since everyone will go for your main in that lineup, overall if they see a 16k hp shrimp. If you use azure fang as an healer (and right now is the only viable setup for her sadly) you'll never gain from ninjutsu, even with 65% mood, as much as you gain from life stat in any outside arena lineup.
