How strong is the Enc summoned pet?

[ClephNote]

Level 49 Nec pet has fewer HPs than level 49 mage air and Necro pets (exact stats found on pet guide on wiki).. Hits for like 3 fewer hps max level. Will double attack and dual wield with weaps equipped, increased HP regen (30 per tick). Pretty much always better than same level Shaman pet.

Will not /pet attack, mob needs to either hit the chanter or have mob rooted on it/kited through pet/mob.

Your call on how useful. I think they are very useful in the right circumstances!
