I feel like I'm misunderstanding wolfpacks.

I've been using them a while with no issue. Chuck a couple at a rocketeer, boom. Chuck a few above a bastion/bombardier, boom. For trials I usually get like 1-2k points per wolfpack, depending on health.

Matriarch trial comes up. Cool.

I load up 20 wolfpacks and plan to just go all in.

Start chucking them, pop bang boom. I go through 6-8 of them before a bastion is summoned in, on the opposite side of where I'm at. Awesome. Throw around 6-8. Matriarch is getting messed up. I throw the last of them, and finish her off with my gun.

Total matriarch damage done: 3800.

What? I was expecting like...30-35k. Not 4k. What is going on here? I understand some of them MIGHT have gone after other stuff, but most of them didn't. Does hitting armor not count as damage?
