Their are roughly two strategies for Druid/Rogue. The strategy you choose depends on who the Rogue decides to focus. There are some finer variations on these two strategies that deal with shaman specs (0/20/41 vs 0/9/52), rogue specs (Mutilate vs Shadowstep) and druid specs (Balance vs Restoration) but the general idea is as follows.

Strategy 1: Rogue On Shaman

A spec with Toughness makes this go much easier. Put Poison Cleansing Totem down, keep Earth Shield on yourself, make sure the Rogue and Druid are purged clean of Rejuvenation and Regrowth. Have your Warrior DPS the target without Lifebloom if possible, but generally you should be starting on the Rogue. When the Druid gets in range for Cyclones, your Warrior should Intercept the Druid and start DPSing him down. When their Druid shifts forms and moves away the Warrior should get back on the Rogue.

You have to make sure you Earth Shock/Grounding Totem as many of the Cyclones and Roots as you can. Also kite the Rogue around your Poison Cleansing totem. Kiting and healing off Wound Poison are key here but don't become overextend. If you find downtime from the Rogue's DPS you should be drinking.

Strategy 2: Rogue on Warrior

If the Rogue decides to stick on the Warrior, switch your Earth Shield to him and position yourself closer to the Druid to prevent him from drinking and controlling his Cyclones/Roots. Now let the Mana war begin. Make sure your Warrior stays low on Wound Poison stacks by keeping Poison Cleansing totem down or in an emergency manually cleaning him if you want to heal big. As a rule of thumb, if your Warrior is above 60% or so drink whenever you can. Scale your Healing Waves rank to conserve man. If he drops bellow 60% and you need time to clean poisons off, have him put on his sword and Board and top him off.

The aim here is to win the Mana war so as soon as you see Druid going for drinks, refresh Earth Shield on your Warrior, have him put on his sword and board if he is low and Ghost Wolf chase the Druid down to keep him in combat. As before, control the Cyclones as much as you can but the priority here remains on keeping your Mana high. Your Warrior throughout the fight needs to push out as much DPS as he can on the Rogue and possibly the Druid if he gets within Intercept range so, as before, keep both the Druid and Rogue clean of Rejuvs/Regrowths thus forcing the Druid to waste more Mana healing.

Notes: In the case of a Balance druid, you will need to mitigate as much of his damage as possible by using line of sight and interrupt rotations. You might have to blow your trinket on a 5 point Kidney Shot and not a Blind if you get caught out in the open and your Warrior can't assist you with interrupts on the Druid or a Fear.

Mana Tide specs for the Shaman will make any Mana war easier but it will be harder to kite Rogues. Both Toughness and Mana Tide are playable with a personal favorite being toughness since you will always be able to get away and drink no matter who the Rogue decides to stick on. Moonfire Rank 1 spam will be killing your totems so make sure you place them right and refresh them when needed.

I don't think I have to say this but just in case, DON'T use max rank Windfury Totem.
