I just went to Mauradon for the first time after having ZF on farm and it was a wipe fest there learning all the new mechanics and pat paths. I think a bit of a learning curve is to be expected.

For ZF, Antu'sul and Ghaz are tough. I started skipping them after I got the gear I needed. My Ghaz kill was probably just luck. I like farming the zombies for xp and I was farming the last boss for the leather head piece that is a rare drop.

I learned a lot about pooling rage on trash pulls to have a close-to-full rage bar when you start boss encounters. That helps a lot for picking up adds (I have a druid tank).

For the stairs, let the NPCs do the bulk of the work throughout the fight. If you AOE or cast HOTs, the new adds will agro on your toons but if you give them a sec, the NPCs pick them up. I just whack one with the tank, frostbolt, then heal when there aren't any new adds to agro on my healer.

For the last phase, I just stay on the stairs and shoot frostbolts with my mages - you can do the whole thing from the stairs. Just burn em from a distance one by one. It's weird encounter..the more you try to "do" the less effective you are xD.

Don't let the guy that blasts the door at the end die! Also, after the event I made a UI change and reloaded my UI and all the NPCs disappeared including the blast guy. Don't know if that was a one off quirk, but be careful.

GLHF!
