I think the trend with survival is extra focus from Serpent Sting. . . As to why I haven't figured that out. . . more arcane shots? Serpent Sting is already granting 3 focus per tick once every 3 seconds. Kinda wondering if SV will be Crit>Mastery>Haste or something? Maybe even Mastery>Crit>Haste? 2P leans this way but with the 4P I'm really confused which direction blizzard is trying to go. . .
MM 2P definitely looks like volley and of course looking at BM is just more pets. it's kinda neat I guess since BM is all about pets anyways so why not more? although the BM 2P "until Cancelled" could be clarified more. . . perhaps a mistake? I understand the chance to "enrage" your pet, but will it last forever then? Who would want to cancel it in a raiding environment other than the obvious stop hurting something as much because of X, Y, or Z reason.
Posted this in the alpha thread, should have been in here....
The survival 4-piece lasts for 6 sec, so it's designed to only stack during LnL procs. So, basically you get permanent 10% haste with more haste after LnL. Not sure what the stack cap is on it (the "0 times" thing is probably a datamining error). Could be nice for Exotic Munitions though. Also gives more value to multistrike since LnL uses it now. All the bonuses seem to be designed to favor each spec's secondary stat attunement.
I assume for survival they are mostly datamining/tooltip/placeholder errors until more information is released. Pleased with MM 4 piece right now, curious as to what the 2 piece will be for it.
2-piece: Activating Rapid Fire also grants you Deadly Aim. Deadly Aim increases your critical strike damage by 10%.
4-piece: Aimed Shot critical strikes have a chance to call down an artillery strike on your target, dealing 10 damage. (Approximately 1.50 procs per minute)
MMOC is missing one, but wowhead had it.
