Shamans are going to kill me for this post, but I doubt the devs will change anything because of it. Someone was asking about Shaman pets, so here we go.
I played a Shaman as my main class back in the day and know more about them than any other class. One quirk to their pet was that they would NEVER equip weapons. Not even for procs. No matter what weapon you gave them, they would always "hit". Not until 2002 did they add the ability for shaman pets to equip weapons. This also allowed them to dual wield. No shaman pet would dual wield (I don't even think the PoP pet True Spirit would dual wield) unless it was given 2 weapons.
Here's a related post for proof:

People wouldn't be going crazy about their pets equipping weapons 3 years after the release of the game if it wasn't something new.
Another thing I've noticed is that shaman pets tank too well on this server. You were always way better off tanking instead of your pet on live, but on here I've seen shaman utilize their pet like a mage, which is definitely weird to see. As far as regen goes, I'm pretty sure that shaman pets regen at the same rate as the others (mage/necro etc). Shaman pets would always regen way "faster" than mage/necro pets, due to having much lower HP.
But anyways, the whole shaman pets equipping weapons thing was such a great turning point for Shaman that thread is one of the dozen saved topics from the old Crucible, along with VT Key, AA guides, etc. It was a huge bugfix that most people don't remember (it wasn't documented), that P99 should never see.
