Sorry for another post, just curious which is better Key to Endless Chambers or Skardyn's Grace (both heroic) Because it comes down to 285 agi with a 1400 mastery proc (on use) all the time or 1710 proc of agi and the hit rating, which i can reforge and reforge other stuff.
It really depends on what you need and that depends on your spec, personally i like the agi proc alot more and offc you can reforge the hit to something more usefull.
Skardyn's Grace
+285 Agility (constant)
The 20 seconds on-use 1425 mastery rating then becomes 7.9 points in Mastery every 2 minutes. (180 Mastery Rating = 1 Point in Mastery)
Key to the Endless Chamber
Equipped "chance" to gain +1710 Agil for 15 seconds
+285 Hit (can be reforged into Crit or Haste)
Tough call, but I'd have to agree with Shahinson ... your current gear/spec should determine what is better for you specifically, since both are nice.
