Heads up, looks like a stealth nerf has hit against afk macro'ing. Seems if there is no character activity after 15mins, the macro auto-dumps. This appears to have occured with CH7 on TCPrime. Will try and verify, but keep your eyes open, otherwise, could be painful for the folks down there on the trail. Also check out the Insane XP post by swghax for another super fast way to get character CL's, this method outlined in this post, however, is the current #1 way to grind that pet fast.
