Farm mounts/pets/achievements. That's all I'm doing.
300 mount reward is shit (I only miss rare spawns/argent tournament/invincible/MoP raid drops), pet battles are shite, and I'm happy with 22.5k... I don't feel like going back to my old self. During Cata, I was the #1 Horde player on my server in terms of achievement points. I spent hours doing horrendously dull shit, but now? I'd rather just not.
So no, no archaeology, no new BGs, no... Anything. Fuck it all until Legion.
