With me hitting 2500 in 2v2 as priest-rogue yday, I reconned I would type out and release my strats against most other top-comps, if you have any questions about comps that arn't listed here please feel free to ask.
The tactics honestly need the rogue to be awake and know when to Line of Sight / Crowd Control / deal damage, practice helps. I get tired of trying to help boost other rogues that think they can faceroll on top of the warrior till there's a win. Enough though, let’s start some strategy talk.
Talent specialisation may vary, but rogue is mutilate and priest discipline, point distribution doesn’t make or break these fights, so use what you find best for you. As far gear goes rogue should be using a darkmoon card: death or the equivalent proc trinket from naxx, sit around 3,4k attack power, priest can do with 1850 unbuffed spellpower and it’s good to have 20.000 health points and 15.0000 mana, so you’re not lacking stats. Resilience isn’t key to winning so rogue can go lower then 400 and priest around 800, though I’ve never tried it lower then 900 (don’t gem for 2v2, but it would help too).
Laying down the law upon druid/warrior (4/10):
Starting out we sap on the warrior: 1) He berserker rages out and we wait some seconds and start on the druid, fear the warrior so he has to trinket it for helping his druid. This is an attempt to force trinket on the warrior, don’t force yourself upon the druid, but you can hope he dies. 2) Warrior sits in the sap, I run in dispelling the warrior and force myself in between druid and war to mana burn/push druid back. After sap runs out I turn around and send in MB, HF and SWD on war while he's stun locked fully (consider staying at LoS objects, not sitting in open when pushing the druid away).
With the start out of the way:
I want the druid out of mana by mana burns / dispelling the warrior WHEN it helps my rogues dps / ruining the efficiency of his heals! This tactic is heavily based on playing the druid oom without even touching him (can easily be switched to however to keep him on his toes, but remember it’s better if he’s on his heels!).
After the starter I use instant on my rouge and mana burn the druid, the warrior is defensive till he's topped. 1) Rogue gouges the warrior and runs out of line of sight and PERHAPS gets a restealth. 2) War berserker rages out of gouge, keep a small amount of pressure on him if he follows the rogue to have the druid healing and then fear the warrior the moment berserker rage is faded, then restealth.
This forces an incredible amount of the druid's heals to be overhealing and he's turtling away from priest from mana burns, so you'd be surprised with the amount of restealths getting off (OOM faster if he tries to keep rogue in combat, so it's win/win for priest/rogue). Continue this till innervate is blown, which is quite fast to do, then get another restealth like always, except this time priest doesn't pressure anyone, but drinks up to sort of reset completely.
After wards you go back to the previous tactic of ooming the druid, blow shadowfiend when the druid is oom and blow up the warrior with it (fear ward shadowfiend so a warrior fear doesn’t avoid the damage). The tactic of ooming a druid gets a lot of shit because it can be terribly hard, but that’s what openers are for. Restealthing makes current heals on warrior ineffective and the burst going into him in a starter can easily make him go 100-20, perhaps 0. Establishing this pressure all of the time destroys the druids mana and honestly it’ll also be a success without the cheap shot opener (don’t you just love rogue failing to open and just getting shouted out of every starter that isn’t a vanish).
The druid doesn’t go oom if he keeps trying to drink, but in doing so I assure you the warrior will die.
Lets now talk druid/ret paladin (2/10):
This setup doesn’t require any effort, do the same starter by chasing the druid away from ret and dispel ret. Blow up ret, he'll bubble the first stun lock (NO KIDNEY SHOT ONLY EVIS, depending on when freedom is blown). Restealth as much as you need sap, open and win due burst. We've never needed to oom the druid in this matchup and there isn't much pressure on us. Resetting in this is just twice as easy as on dru/war, so play it calmly and you’ll win.
Druid/deathknight (8/10):
This matchup can't be beat unless they make the mistake of letting us win. We try and usually succeed at getting innervate used early. After this point I need to get my mana up to the druid's level. We take down the pet then throw up a gouge on the dk, fear and stun lock, gives time to get some mana even if it's not from drinks. Then we repeat CC on the dk/pet a couple of times like this, I'll send out some burns and eventually it's possible that the dk goes down from sheer dmg and oom druid.
However this can go on for 20 minutes, so it's not a setup we can particularly outskill. We're always on our toes from the pressure coming out of the dk, they can very well play it out to 45 minute draw as easily as we can. As such I don't have a 'I WIN' tactic for this setup, I only have a test of concentration, which we tend to win consistently.
No matter how well these strategies are explained I still don't believe most people can pull this off without some/a lot of practice. My rogue didn't believe PR could stand a chance against druid/warrior at all. It's all about knowing everything about the opposing team when they do anything, I for one call out bladestorm before warriors do it or else we'll just take too much damage (can tell from if they’re comfortable or not and ofcourse the sweeping strikes). I haven't played as successfully with other rogues either, because it takes time molding the rogues brain to the concept of completely countering the warrior class in every single aspect and playing on the fact that fear control works damn well on warriors.
These strategies work without fail and teams can try to adjust to it, but they cannot win, which is why I’ve held back with revealing it. So far my team just hard counters druid/warrior or druid/ret paladin and it's not something I want going on all over and ending in nerfs again. Note that druid/deathknight tactic doesn’t fail at playing stalemate, still wondering how to outplay them.
