I've already seen confusion in casual chatting about Arcanist. I've read things with people talking about ARC and then suddenly after halfway through their thoughts I realize they're talking about Arcanist. I can only imagine this will get worse when the Arcanist is actually in the game. Arcanist's official abbreviation is ACN, I believe, which is good.

Perhaps out of clarification we can think about a change for Archer? Perhaps ACH or ACR for Archer.
