Perhaps the most difficult combo for Druid\Hunter to beat. Start off as usual, with a flare on top of you and your Druid, and drop a Snake Trap. Get the Rogue out and start DPS on him as soon as possible. Put your pet on the Warlock for spell interruption.

If they go on you, you're probably in trouble. You must get away from the Rogue so Wound Poison doesn't build up, and you don't take too much damage. Essentially, what can happen is the Rogue solos you while the Fel Hunter eats your HoT's and the Warlock Fear spams/Deathcoil/Blinds on your Druid. It's impossible to live through that, so you must interrupt it with whatever you can, Cyclone, LoS, lucky Abolishes, whatever it takes. You must kill the Rogue as quickly as possible. Keep a Scorpid sting up on him, and Scatter Shot after your get Crippling Poison removed. Viper Sting on the Warlock, forcing him to Life Tap and Silence Fears only.

If the Rogue and Warlock go on the Druid, you're almost free to DPS the Rogue down, while you do the essentials, like Silencing damage from the Warlock, and Scattering at good times so your Druid can get away. Kill the Rogue, and don't let yourself get CC'ed. Don't let your Druid die; you may need to spam Wing Clip on the Rogue for the first minute or so of the game. Flare should always be near the Rogue in a position that you think he may go in pursuit of your Druid.

Druid's Perspective
I hate this combo so much. Again, they may go on you or the Hunter, so when you pop out, HoT/Abolish yourself first if the Rogue hasn't popped out yet. This fight requires more communication on positioning than any other combo in the game. You need to constantly be talking to each other about where you are and where you are going to be moving to, so you can stay out of the LOS of the Warlock to avoid fears while maintaining LOS on the Hunter to keep him healed.

If they're on the hunter:
Do not cast until the Warlock's Fel Hunter uses his silence. Getting counterspelled can be a game ender. Don't let it happen.

You need to constantly be aware of the Warlock, most teams will simply have the Warlock DoT the Hunter, the walk over to you and do NOTHING but fear...fear...fear...(blind from rogue)...fear...fear...fear, with a Deathcoil when you trinket out to continue the cycle while the Rogue kills your Hunter. He won't DoT you because DoT ticks means fear could break. So, you need to be next to a pillar and watching the Warlock carefully to avoid getting feared in the first place. Keep Abolish Poison/Lifebloom(x3)/Rejuv up, Swiftmending whenever possible. If the Warlock gives up trying to fear you and starts nuking the Hunter, you can come out and pump fake a Cyclone to bait the Counterspell (If they give up they will watch you very carefully, so they will almost always fall for this).

Keep the hots up, and eventually the Rogue will run out of cooldowns. When he does, he will get kited and then killed. This game is simply a matter of how good you are at avoiding the fears.

If they're on you:
Frost Trap owns them. Keep Abolish up, Rejuv/Lifebloom, and kite around the Trap/Pillars. Your Hunter can help you here; you need to communicate very, very well. When he gets feared he should be screaming, "I got feared", if you're ok and can survive, tell him that so he can save his trinket for the next Fear or Blind. If you're not ok, you need to let him know so he can trinket to help you out via Scatter Shot. If you see the Rogue blow their trinket, you can then use a Nature's Swiftness Cyclone to buy yourself 6 seconds to get away from him.

Delay the start as long as you can so you can pick up the Shadowsight, this way he can't do a Blind-->Sap combo in which they can kill your hunter.
