Because this was briefly touched upon in another topic, I'd thought with some of the Emissaries being immanent and some time passing since the first discussion about the Emissaries, it'd might be worthwhile to talk about the various Emissaries.
Somebody else mentioned the Carrion Emissary being the strongest, and while I agree it's strong, I think it at least shares a place with Shadow. Not sure if I even made a list without the Shadow Emissary in the past months (mainly Lynch & McCabe).
Then somebody mentioned Arcane Emissary as the strongest, which surprised me. Haven't played it yet, but from I gathered, most Arcanist players found it pretty lackluster?
