Does anyone know if this is battle-net account bound, or just subaccount bound? Everything I've seen says "account," and I'm not sure which one that refers to.

Since humans gather rep faster, I've put a level 3 trading post (+20% rep) in my human's garrison, but I only have 1 human on my main team.

I guess the question could be phrased "are achievements (including the meta-achievement Draenor Pathfinder) shared across all your accounts?"
