Question on your example:

"Ninja A got combo'd by Jonin Minato, Madara 5ks, Kurenai and Fire Main talent 43121 chase KOH. The order of the debuffs will be: Tag, Paralysis, Acupunture, Chaos, Ignite, Poison, Ignite.

Tsunade heals Ninja A once, Chaos will be cleared... Tsunade heals Ninja A once more, Acupunture will be cleared."

You mentioned chaos will not be cleared first when paired with priority 1 debuffs (acu + para in your example). Also you mentioned that debuff clears in reverse order of application (latest first) if same priority. Thus in your example, shouldnt Tsunade be clearing Acu first, then Para, instead of chaos then acu?

Cool, just sanity checking hehe. Thanks so much for this, was always curious... But too lazy to research :p
