I'll just keep saying it and hope that people stop wasting money on obsidian to their own peril.

They have been making changes every patch since 3.0 to clearly and obviously phase out Obsidian gear. It is wise to work on erenor gear and gradually transition into that.

Obsidian probably doesn't have a future and it hasn't been the fast track gear since 3.0. Ayanad is the fast track gear and will continue to be the fast track gear.

Don't believe me? check omnom.io and read the 4.5 patch notes. It's pretty obvious guys. I felt the changes in 3.0 made it pretty obvious and literally every patch since there has continued the trend.
