Getting bored with my wizard and had an idea of making a pure druid which I know is EE viable but was thinking what if I made a TF Mortal Fear collar & shadow scale armor for my pet?

With 3 past lives druid, and augment summoning from the Mystical Elodiens necklace while buffing wolf up with magic fang, pack presence, animal growth, pack aptitude, & tenacious pack.....would the pet be somewhat useful?
