I discovered something by accident yesterday. I've been trying to start the family familiar achievements, which means doing each pet battle 4 times across two accounts. Historically the first account you log in "locks" the pet battle interface, and the second account cannot battle until the first account has logged off and the second account has /reload ed. I discovered yesterday that using my heal pet ability (while running pet tracker, not sure if that matters) unlocks the second account without the burden of a reload (still requires the first account to log off, though).

I don't know how things are affected if you are using more than 2 accounts at once, just thought I'd share this tip for saving 10 seconds a few times a day.
