Hunter has a very critical bug right now, it has been 17 days since launch and still no word from Blizzard.

b if I sick my pet on the target, many times it'll run at it, especially if the mob is already running towards me and somewhere else, it takes a few seconds for it to finally hit the mob with anything, whether it's growl, auto attack or bite

What kind of pet are you using? I'm using a Cat and previously used a Boar and haven't experienced this at all.

c. on both defensive and passive, I do see it often that my pet will just sit over the corpse for a few seconds doing jack all before coming back to me, though if I tell it to attack someone else it will

I'm generally fast about ordering my pet onto a new target, maybe that's why I'm not seeing it.
