Help, Im phased in Durotar Undercity and more

I could use some help, I am out of phase in Durator Undercity and a few other zones.

I have been searching the helps looking for which quest I need to do but I can seem to find any that I can do.

I have been at this a few weeks now doing all the quests I can find to try to get myself back into phase.

If any GMs might be able to tell me which quest i need to do to get back in phase I would appreciate it.

Thank you

Dorteler
