When I tested it out it seems like it autosummoned much less than one per round of the smaller boars, small enough numbers that it was not worthwhile as anything other than a small bonus. It's size 5 so less effective than elephants at trampling, is a leader but with only two misc slots there's not much worthwhile to put on them, they've got low protection so you need many of them to have a chance of survival, and being sacred doesn't help much as you're unlikely to have a good bless. 7N doesn't sound too bad, but when you're talking about summoning 10 of them in order to be effective those gems start adding up fast (smaller numbers than that are going to struggle against even strong PD). I'd rather have 4-5 equipped druids almost any time.

That's just my opinion though, you're perfectly free to hold your own and prove me wrong.
