Check out Tier 4/5 armor

[Alias]

the Blizzard site has updated the armor page to show the new tier 4 and 5 armor here

I thought it was interesting that the druid, shaman, pally, and priest sets have multiple options catering specifically to certain specs. that does make it a really big loss to change spec at lvl 70 after getting a few pieces.

It is possible to get all of the sets. Time consuming, but possible.
