You notice that also, hum ?
There are several wrong things with his list. The existence of it not being the least problem.
The value of a piece of gear can only be determined by looking at the whole gear set. In any case, all secondary stats only have the same value is you are running Patchwerk-style sims. In most cases, specially when there is AoE involved, or when you need to stand in front of the boss (which should account to most of the raid fights these days), you want to cap hit and expertise first (the different for AoE is huge). Then, you want to keep your other secondary stats BALANCED, maybe we haste slightly ahead (specially if you are using the Matrix trinket). Try going all crit and you will see describing them as all the same just won't cut it.
Also, the BiS list for trinkets here doesn't work. BiS trinkets are Compass and Wrath. You don't want all 5 pieces of T13. You want 4 plus Underdweller's Spaulders.
When you do all your math, you will see your BiS neck is Choker of the Vanquished Lord (397), so thats 2 BiS pieces from H-FL, not DS or VP.
Also, be very careful with set bonuses. 4xT12 is very strong is you are hit/exp capped, specially if it is 4xH-T12. If that is the case, you might want to delay going T13 until you get 4xT13 or 2xH-T13. Forget LFR-T13. Speaking of LFR, there are 2 pieces you want regardless of Heroic FL gear: the Wrath trinket and the Kiril polearm. They will be upgrades regardless.
My strongest recommendation is: forget BiS lists for feral druids. Get Mew and/or Rawr and work what pieces are upgrades based on YOUR SET. No piece works alone.
