Since 2.3 has come out I have only played this combo twice in high rated arena(Coincidently the same night as of creating this writeup). The first game Chances and I played in it for an hour. At first attempting to just stay on the Shaman and Drain him. Then by draining the Shaman and DPSing the Rogue. Neither of those worked, Shamans are IMPOSSIBLE to drain. We won by coordinating massive CC on the Shaman and killing the Rogue, the second game after doing this was won in a total of 4 minutes.

The Rogue was specc'd into Mutilate, so that's the only way I'll be able to explain it. I will tell you step by step how our second 4 minute game went versus an hour for our first game.

It was Blade's Edge Arena, we charge across the bridge and upon recognizing the Shaman I decide to go ahead and flare to which I got a lucky spot on the Rogue. From there the Rogue charged at me and did damage, my Druid did various CC's on the Rogue, I went to the Shaman, destroyed his Grounding Totem, Scattered and Freeze Trapped him while the Rogue was Cycloned.

The Shaman trinketed the first Cyclone and threw heals on the Rogue, no biggie, 30 seconds later we attempted the same thing, getting the Rogue to around 30% before the Shaman got a quick NS heal on his partner(My druid assisting me in DPS, keep in mind he's specc'd Insect Swarm), which was pretty amazing to me because the Rogue was using all of his cooldowns on me and Mutilate has a nasty poison dispel resist.

At this point I had not used Stoneform and neither of us had used Trinket. I was preparing for the next round of CD's, so after waiting for him to finish his cooldowns, we then opened up for the kill shot.

Pretty much flawless play, the Rogue was rooted, and already at 75%, I killed a Grounding Totem on the way to the Shaman and scatter trapped him. Put more pressure on the Rogue, my Druid did a double Cyclone rotation on the Shaman with me getting a Silencing Shot in between while my Druid had to trinket a blind. I used trinket to get out of Kidney Shot, and Stoneform to keep range and got the kill shot on the Rogue with my pet while he was attempting to LOS me at 5%, and the Shaman was Feral Charged and Bashed.

So as you can see above, having all your cooldowns/trinkets up is really important for the kill shot while they have NONE themselves. Your Druid needs to be assisting your DPS and on point with the Cyclones. It really is easy, don't attempt to drain the Shaman, it's a waste of time, our first game was over an hour by attempting to drain. The Shaman idled at 1-10% mana for 30 minutes before we gave up attempting to drain the Shaman. Stuck to that final strategy and like I said above, we went from a 1 hour game to a 4 minute game.
