OK, sure, but that’s trivial compared to the damage boost to other effects. I tend to forget about it. ETA: I’ll also bet it doesn’t register that damage if your pet isn’t attacking a target at the time, which is what seems to be happening.
I looked at what you’re talking about and it really looks like your pet isn’t actually participating in the combat except when you send it in for a Kill Command.
I know how I can get that to happen with my pet. Let me log and and play around to get some details to share.
Edit: I can sort of make something similar happen if I’m having my pet move a mob. If I send the pet in to attack, and then put the pet on “Follow” so it comes back to me, kiting the mob, then until I do a PetAttack again, the pet will do Kill Command on demand, but then immediately come running back to me. But even then, at least in Details! logs, I still show some melee, bite, stomp, beast cleave, kill cleave, etc. damage.
But that goes away in the next encounter. I suppose you could go a whole boss fight not noticing, but doubtful that could happen multiple fights. Even if you keep your pet on passive, it will commit to the fight the very first time you Kill Command. You have to explicitly put it on follow, I think, after the fight starts.
It’s very strange. I’m sorry I’m not more help, but what you’re seeing is definitely unusual and the way your fellow hunter’s logs look is more the usual thing you should expect. “Stag” is just one of his pet names.
Do you also run Details!? Can you look back in your Details! logs for those fights and see what it says your pets were doing?
