The core responsibility of tanking is to hold aggro, to direct incoming damage towards yourself instead of letting it hit the party, or failing that, to try and reduce it.

Restoring HP to yourself or the party has nothing to do with that. That's for the healers to take care of. That's why they exist in the tank-healer-DPS trinity.
