Well dual dps @ dual dps. The usual idea is to bomb the mage, but with ice block and their ability to kite you'll be wasting time, cooldowns and health. Beware Human opposition.

You'll want to take out the opposing rogue via bleeding and stuns, just drop a bomb on the guy. If you're having trouble finding the rogue here's two things you could do.

Number One
Rogue #1
Do a fake garrote opener upon the mage, once you see the rogue vanish and quickly reopen upon him full guns ablazing with your partner. You may wish to trinket a Kidney Shot if the rogue opens upon you with a full lockdown, but be careful of future CC and alert your partner to hide if it reaches that point. Hit the mage with a blind after your partner forces the trinket with his. Run and bandage once you finish the rogue if necessary.
Rogue #2

Recently I've been running into some bad 2v2 drifting on my part; however, I've finally found a steady partner to play with, and I have to say this is probably some of the most fun I've had in arenas. Dual rogue is a very simple combo, but at first it can be difficult. If healer/rogue or Caster DPS/Rogue isn't your thing, then this is definitely for you!

Talent Builds
Undoubtedly Shadowstep is just the way to go nowadays. AR/Prep used to be the prime choice, but really it's just not worth it anymore.
One Rogue will definitely want to take a build like this:

While the other may use a traditional 20/0/41(With full lethality), but definitely grab VP either way you go.

Gear/Gems/Trinkets
Gear: This combo calls for some good damage AND survivability. Definitely grab 4/5 Vengeful and have the rest be about T6(if you have access to such gear). Gem all offensive with either Crit, AP or Agility gems.

I like to think of this team as a nerfed Druid/Lock simply for the fact that they have a lot less crowd control and a pally can't even kite half as well as a druid.
Rogue
Alright well as soon as the lock sees your partner you just off the bat you know he's going to sick his pet on him. So go in for the sap real quick, then go all out on the pally. Be aware of CC from the lock, and call out the pally's bubble. Do everything in your power to down the pally, but also be cooldown smart. Once the pally is down take out the lock's pet to give your partner a little breathing room
