It is quite powerful but as a Personal rule I tend to keep at least 1 Medic in the team to remove debuffs. Remember, what you do to them they can do to you.
The Debuff Reflect also doesn't seem to stack so if someone starts the combo with ignite or poison, they can and will apply acupuncture or immobile to your team as well. If someone faster than you comes along with this exact combo, your team will not be able to recover from all the acupuncture before you fall so you must play your team very very carefully.
Just a thought.
It doesnt stack but the only time I get a debuff it ends up on Tobi and then he dies thus removing the debuff :P I replaced hinata with Ao recently though so the clones and shields help out a lot with debuffs
