The problem with summoned units like the wolves, is that you can't buff them with the usual buff possibilities you have on other skills (bonus to damage, elemental damage bonus, basic ability bonus, item damage bonus). Now some of these might work, I haven't played with it too much. But one other problem is that summoned units often have physical damage too. Which means that you need a way to strip the monsters of their armor in order to do any damage.

I just don't think it is possible to make the wolfes scale enough. It may be a pretty neat leveling item, but I don't see it working at max level.

Skywrath mage can spawn infinite of them, which helps the wolves to not be that useless...you can also use some kind of armor penetration stacking with the armor reduce gloves or something.
...Anyway, it's too wonky.
