I could look at transferring some toons around. I have been playing solo for most of my time in MoP, only just got back into boxing very very recently.

The warrior/DK/healer does seem promising, though I think I would need to wither gear up my DK/Healer, or simply wait for WoD. I think that looking at doing 3s may be my best option. I have enough toons on my single account that I could look at moving a few characters through quickly enough in order to maximize arenas.

As far as Ashran goes, I don't think /follow will be coming back. But IWT and extra seater mounts are still working by spamming IWT. Almost to the point where it's as good as follow.
