This is a pretty easy fight and not one you should ever lose. The only way I can really see this team winning is if your Druid is poor on CCs, their Druid is excellent, and they burst you, the Hunter, down. Between Roots, Cyclones, Abolish Poison, Freezing Traps, Wing Clips, and everything else you have that their Druid can do absolutely nothing about, you can kite their Rogue all day long.

If you feel like it, you can start mounted and rush forward, dropping a flare at their entrance, or where they might be on the bridge at Blade's Edge, but a much safer approach is to run up and flare where you're going to stand. Your Druid needs to stand in your flare for most stealth teams; don't stop using flares once the fight starts, you can nullify the Vanish. Place your pet on the Druid; the Rogue will go on it if he wants to win the game. If he kills the pet, it means you were poor with heals, CC, or pet control. In any case, pull back and start to Revive your pet, then send it back on the Druid immediately. Do not let the Druid drink; this game is already long enough without a Druid getting drinks.

Don't allow your Druid to get low on mana, or you could put yourself in a situation where the Rogue gets his CD's back, and your Druid gets CC'ed and gets OOM.

Keep Vipers up on the Druid; coordinate CC on the Rogue, and DPS the Rogue down. Again, probably the best tip I can give vs. Druids is to coordinate bear to humanoid bash and viper stings.
