I saw the other post, but as I'm not 100%, I didn't post. Should be class +1, maybe +2. A berserker in Knight with the Inquisitor and a golem for example, cannot buy a pet if memory serves. I might have finagled something along the lines of calling the Inquisitor after having the other two charmies but my memory is fuzzy. I'm not sure if you can do that with a necro or beastmaster. I'm fairly sure that a beastmaster in Knight (again by example) can't get an Inquisitor with a full horde but might be able to call horde after.
So if you're wondering if a necro can get two animated minions, a summoned minion, two golems, cabal pet, mournblade (pre-change ... not sure about post), mercenary and [other] for like 8-9 pets, no.
Short answer: I'm not entirely sure.
