So, one of the more exciting and difficult challenges in your WoW life is when you enter an arena to discover a healer + dps team. These come in a variety of combinations, so we will just keep it general and not address each combination directly. Let us explore two different strategies:
#1) Your team is also Healer + DPS.
This is a difficult fight for a hunter for one main reason: Mana. Most HD (Healer/dps) teams have someone with limitless attacking capability. So, your time is limited in each encounter. Here are some general tips to try and follow:
A) Keep the mana sting up at all times. To avoid instant cleansing you can spec into imp sting (highly recommended for an HD team entering arena). Most matches it should be on the healers. The exceptions to me are when the other team has a mage or hunter. Those two mana pools can be drained and make the healers ability no longer important since they cannot kill you.
B) Use LOS against them! Healers will surely LOS you and this is so great if you use it correctly. Make sure when they LOS you that your healer is dragging their dps to a land far far away. Then when that healer starts to pursue, BAM! Hit em with your CC, rapid fire aimed shot, etc. Also, line of site their dps right back. Of course, vs a warlock this won't work. Against moonkins, mages, other hunters, elemental shamans and pretty much any melee this can work nicely. Drag them around a pole as your pet beats on them and your stings tick. The longer this lasts, the better for you.
Also, make sure those mana burning priests cannot get any burns on you. Stay near a pole and dance back and forth trying to land a shot or two and then avoid the burn. Priests can drain a hunter faster than should be allowed, so never try to stand and take the burns.
C) Be diligent on CC. Remember to fear beast when you can, sleep when you can and trap when you can. Try not to get away from this. Even after all the nerf's, crowd control is still boss. Most dps won't survive the full 10s without their healer. Especially if it is the fifth time you have done it to them! :)
D) Fight in Viper...ALWAYS. This cannot be stressed enough. Viper in arena. Smash it into your head.
E) E-bay - Buy yourself a warlock and then find a resto druid. This will make you forget you are playing a hunter/healer team and without gear or much skill you will make your way to 1700 in no time! Sorry, I am terribly bitter towards locks in arena and pvp :(
Ok, what if you have a DPS + DPS team? Forget support, brute force FTW! Here are some good tips for a double CC team...did I say double CC, I meant double DPS! :)
A) CC like mad - Especially if your partner has no ability to heal at all (rogue, warrior, etc.). Usually one or two timely crowd controls means someone dies. This is extremely difficult vs teams that can remove your traps. If possible, trap the person who can remove your cc to solve that issue.
B) Aimed shot - Usually I like to say only use Aimed shot under a rapid fire, BUT the exception to the rule lies here. An aimed shot can mean that you do indeed win via brute force. Force that healer to try and out-heal your dps with that reduction. I would NOT recommend any aimed shot if you are under attack unless you can do it without interruption. Let's just hope they focus your teammate!
C) Don't let them use LOS to beat you. Make them use LOS to lose to you. Let that healer hide, drag his dps away and burst him and when the healer pops back, CC them right away and burn that DPS down. This will be especially hard with resto-druids, so try other approaches on them. A lot of times you cand rag the dps over and when the druid comes to save him, immediately start your aimed shot on the druid. You accomplish two things, your debuff on him while he is healing his partner and catching him in leather armor. Now he has to decide who to heal and that choice could really sway things in your favor.
D) Pay attention and learn. Some teams will seem unbeatable to you at first. Especially warlock-resto druid. Try to pay attention to what works and try new stuff. Kill the locks pet a few times. Try to rapid fire down the lock. Whatever the case may be. Make sure you watch and learn. So, next time you can try again with something new until you find what works for your combination. Just because hunter A beats mages with LOS, doesn't make it fact. use what works for you through some trial and many many errors.
Being a hunter in arena is hard work. Do not expect easy success until you are geared well. Also, be patient. It is gonna be hard for most hunters in arena. Try to work with your spec and mold yourself for what you need help with. Sometimes, it is as easy as getting wyvern sting :) Go in to arena to have fun at first. After you get geared up and "seasoned" ...then go for the glory!
As always, ask any questions you may have! I will try to go into more specific combinations eventually, I swear!
