The best possible gear including gems and enchants
This set of gear is suggested by sim with following settings:
all clss buffs "on" except for Imp. Faeri Fire, Trueshot aura, Ferocious inspiration, Improved SoC
12 shocks per 2 minutes, wait 3 sec with SS if WF on cooldown, 6200 boss armor
Results from the sim: dps = 2075, dps value of 1 additional EP = 0.4 Lootrank link with EP values
Some notes:
Main: S3 > Syphon=Talon > Dragonstrike
Off: S3 > Syphon > Rod
Insidious Bands = Deadly cuffs
Shoulderpads of the Stranger = Swifstrike shoulders due to expertise rounding

Blizz itemization for us has been so poor (mana per 5 sec..., bad stats distribution ), that best set (suggested by sim) contains only rogue leather items with one hunter piece (legs).

Assuming that Sunwell loot has iLevel =159 for set pieces (T4 = 120, T5=133, T6 = 146), iLevel = 154 for non-set items, iLevel = 159 for loot from end-bosses, using Item Level formula from wowwiki (very accurate), using EP values from sim from the best set available, assuming that there will be 7 stats on chest piece (as it is now in pvp chest), further assuming that only non-set pieces can contain no stam/int, it is possible to theorycraft chest armor that will be scored highest with abovementioned EP values:

Elitist Jerkin
Binds when picked up
Chest Mail
1078 Armor
+20 Strength
+15 Agility
Durability 140 / 140
Requires Level 70

"Yo!"
iLevel = 154
626 EP (Midnight is scored twice less)

Another theorycrafted piece of gear possible within iLevel = 154 that you can find interesting:
Dark Naaru Paradox
