Cat is my offset/spec but we've been farming for awhile and I have all 277 pieces except for the t10 tokens & second trinket (vanquisher hates my guild).
I appear to be coming up on the crit cap.
Before reforging Mew told me that Haste was my least valuable stat by far. After reforging all haste it turned out crit was lower, so I took the 2 pieces that had more crit than haste and reset them & reforged crit to mastery. I happened upon the exact point where crit *just* fell below hit/exp and matched haste.
As I upgrade to the ilvl 277 tokens I think I'll be in a conundrum. Crit is basically worthless to me now, UNLESS I get more hit/exp, but AGI is still the best thing to gem for, and mastery is still the best thing to reforge for. So I have no source of hit (unless I pick up gear that has it natively).
I'll have to take a second look at the following. I miss Rawr & optimizer, mew is nice but playing with entering stats is annoying :/.
[Ikfirus's Sack of Wonder] (I would still reforge something into mastery)
[Gangrenous Leggings] (druid legs already have exp, pass)
[Geistlord's Punishment Sack] (losses too much agi over t10, pass
[Band of the Bone Colossus] (perhaps)
[Ashen Band of Endless Vengeance]
[Signet of Twilight] (wtb)
Also semi-interesting is what do gem/reforge the eve of the cata release. Increasing dots on bosses is fine and dandy, but 80-85 is mostly going to be mangle spam.
