The paladin spams cleanse and uses holy shock + BoSac after they start the opener, while the warrior goes on the shadow priest. Once the warrior gets under 60% the paladin divine shields, the warrior hits a battle stance/shield reflect macro and gets ready to pummel a 1.5 second mass dispel.
Any good warlock/shadow priest teams know when the divine shield is coming, so you need to be quick on the shield bash. The shield reflect will typically reflect a death coil at high rated play, and if it doesn't, you just shield bashed a mass dispel, then you can trinket the next death coil and intercept.
yeah you used one of those terribly unclever fad-phrases from the WoW official boards. Clearly I am owned.
I play 2v2 with many people. One of them is a rogue who is currently wearing bonescythe and a blue tbc dagger because he doesn't have any better. As you can imagine, we are highly disadvantaged against the 1600-1800 masses of war/pal teams who can't bust through the caster wall they end up hitting later on. Yet an actual fight occurs, they make mistakes we can occasionally exploit, we try to a few unpredictable strategies, we make mistakes and rectify them later. We still end up losing often. Being at a "disadvantage" is completely different than being 100% unable to control your character while all your hp/mana is removed.
If your partner is letting you get chain feared, he is doing something wrong. It is terribly easy to kick/pummel, stun, etc. A rogue beating on a warlock makes a fear take ~3 seconds to cast, and a warrior that lands just 1 attack on a warlock in the middle of a 1.5 cast turns it into a 2-2.5 cast. If you communicate with your partner on when to use your HoJ and when he will be interupting something, you can lock down a warlock for a very long time.
Pallies are at a disadvantage because they need to be in line of site of their partner and motionless to heal. Just because you are in line of site of your partner doesn't mean you have to be in line of site of the warlock though.
But yeah, warrior/pally against warlock/priest isn't a fair matchup. It's not supposed to be. Saying that it takes absolutely no skill for a warlock/priest team to beat you is simply not true though. I ended last season at around 2280 2v2, and we didn't win every game against warrior/paladin teams. There are some games where you just get lucky, your partner gets a couple crits or you resist a fear/spell lock/etc, or maybe your warrior's fear sends one of your opponents to the far side of the map and you have enough time of 2v1 to kill his partner.
