New Pets Types - Tank and Heal

There are already offensive and buff type pets, why not have pets that tank and heal as well?

Tanking pets would have extra health and armor, but also a taunt or some other mechanic to pull in enemies (like the void bomb without the boom)

Healing pets would lean more to the support type pets, but would get a skill to lay down either health pick ups or do a temporary zone of healing.

I think both of these ideas would help the early and mid game for any ranged, magic, or summoner build, and probably help all game with the explosive builds.
