My questions are mostly clearing up what I assume are semantic issues.

1. Under the new Lightning Main Passive Hearth Flux, it states "...your unit will increase it's attack by 2%". Since unit can be both singular and mean a squad or team, in this instance does it just mean your main gets the buff - or the entire team. I assume the former but just want to clarify.
2. Onoki and Danzo have somewhat strange (different) wording for their barriers over the others. I assume it's just a little oversight but both of them mention they give their buffs if there is "a" barrier up instead of directly referencing their barrier ("the barrier") as the others do. I assume it's not the case, but do these guys give their buffs if someone else on your team has their barrier up instead of danzo/onoki's?

3. The auto-stage changers fields - are they ONLY influenced by team initiative or does positioning have anything to do with who's field overrides the other's?

I assume that the field effects are removed when an opponent uses their buff cancelling mystery/abilities, yes? Like Mifune using his mystery after a darui casts his field would remove the buffs.
Will the mifune mystery remove the effect darui has to launch two attacks when under his field effect?
For fields that increase two types of chakra elements (again in darui's case: water and lightning), will they have an extra damaging effect on ninjas that have mysteries utilizing multiple chakra types under the field? Or is it simply a one time buff to the covered stats of a ninja based entirely on their base element with no correspondence to the damage types they use.

Thank you for taking the time to answer our questions.
