Here's a BiS list for all 3 Warlock specs for 4.3
http://simulationcraft.org/430/Warlo...-scale-factors
These are the current scale factors for all 3 specs. The priorities changed a little so I'll write it out. Of course all of these stat weights may depend on gear so Sim your set up for accurate results.
Demonology: Int>>>>>Hit(until cap)>>>Mastery>>>Crit>>>Haste
Destruction: Int>>>>>Hit(until cap)>>>Haste>>>Mastery>>>Crit
Affliction: Int>>>>Hit(until cap)>>>Haste>>>Crit>>>Mastery
The two big changes are to Demonology and Destruction, with Demonology picking up Crit after Mastery instead of Haste, and Destruction using Mastery after Haste. Be careful with these stat weights though, because the official sims do not display a scale chart, meaning for Demo, Haste could be above Crit until a certain value such as the next dot tick. For Destro, Mastery picked up some weight, most likely due to Shadowburn now benefiting from our Mastery, and our fire spells receiving buffs with corruption and BoD doing a smaller percentage of our damage. Still be careful with this since Mastery is only .0064 ahead of Crit.
Now on to the BiS list. With the information currently available, it seems like our gloves will yet again be our off-piece due to the glove drop off of heroic Deathwing.
There seems to be a shortage of available 410 items in certain slots such as our neckpiece, so we may be stuck wearing 397 VP gear or BiS T12 gear in some slots. The current patch on the PTR is of course not a release candidate yet so they may still add some items, but for now our BiS list does not include full Heroic DS gear.
Head:http://ptr.wowhead.com/item=78702
Neck:http://ptr.wowhead.com/item=71472 will be our only available neck choice next to the JP one
Shoulder:http://ptr.wowhead.com/item=78749
Cloak:http://ptr.wowhead.com/item=77098 397 iLvl
Chest:http://ptr.wowhead.com/item=78730
Bracers:http://ptr.wowhead.com/item=78417
Gloves:http://ptr.wowhead.com/item=78461
Belt: http://ptr.wowhead.com/item=78391
Legs:http://ptr.wowhead.com/item=78721
Boots: http://ptr.wowhead.com/item=78449
Wand: http://ptr.wowhead.com/item=78392
Rings: http://ptr.wowhead.com/item=78490 and http://ptr.wowhead.com/item=78419
Weapons: As warlocks we will have 2 weapon choices this upcoming tier http://ptr.wowhead.com/item=78477 and http://ptr.wowhead.com/item=78418 I previously thought that me may be able to choose the dagger from Deathwing as well, but as there isn't a single off-hand available to warlocks this upcoming tier our choices are restricted to the two staves.
Trinkets: We will have three new trinket choices to consider http://ptr.wowhead.com/item=77995 http://ptr.wowhead.com/item=77991 http://ptr.wowhead.com/item=78000 WoU will be BiS for all casters, since 990 static int is impossible to beat. After that you have the choice between ICM and CoC. ICM's proc is rather insane, meaning this choice will come down to how often CoC will proc and how much it will hit for. It will also be important to find out if it benefits from our SP, crit, Afflic's Shadow Mastery or Demo's Demonic Knowledge. For Demonology, MWC may still be a viable trinket option, especially on fights where two DG's are possible.
Again so far 4.3's loot table is rather disappointing, with us not being able to pick up a 410 neck or cloak, not being able to use a dagger due to no offhand being available, and the rather stupid VP system which restricts our gear choices to exactly 1 item per slot, unless they implement more gear or give us a system similar to the firestone vendor.
This is actually the best possible scenario since it will be up for every single demon soul. Me happyICD is 2min so kinda meh
