Icecrown Phase Issue

I do my dailies on 5 shamans for gold. I do not use the Deathknight. Well with the new Icecrown 5mans, I'm finding that my tank is not in phase with my shamans. This occurs when they are dead and alive in front of the Citadel. This is very annoying and time consuming because during a wipe, I have to fly back twice because the shamans can't see the DK to follow.

I have unlocked the Shadow Vault dailies. I had not done any Argent tournament quests, so just today I became Argent Valor. I sure hope I do not have to become a valiant to be phased into the area. That will take another 5-6 days. Anyone have any ideas which quests, etc I need to do to be in the same phase at the graveyard outside ICC?

Have a similar issue, my shammies have done all the quests in that area while Dk has not which is making spirit runs to latest 5 man content highly pain in the arseness. Solution, do all the fricking quests *sigh.
