god comp kill mage -> wyvern spriest and trap the other guy and blow up the mage
beastcleave go hunter (some people go enhance idk why i feel hunter will die a lot quicker)
tsg i'd say probably go warrior, with a monk healer the dk wont really ever die if the monk is good
Oh gosh some of this is very wrong. I've played PriestHD so much this season as well as the other forms of hunter dk x so I will give you pretty much every strat you need OP. So, assuming you have a priest healer you actually are going to do this:
Vs WMD: you aren't going to wyvern warrior much, you're actually just going to asphix the druid whenever you can and after that you can just wyvern trap if your priest cannot get a fear off that asphix in the opener(this will apply to almost every mage druid team). Tunnel mage as hard as possible, trapping off scatters/asphixiates is actually bad mostly with priest because of how your cc chains will work out, it makes it more awkward for priest to get fears, and it is very important you just enable your priest to get as many fears as possible.
Vs Godcomp: Okay spriest is actually your best target for this match up, we used to go mage a lot, but have found spriest is the best kill target. Hunter DK X just destroys shadow priests, a good mage is going to kite the fuck out of you. Usually what we'll do is if they prehot the shit out of the shadowpriest, we'll hit the mage for a couple seconds but not pop any cds at all onto him, and then we'll swap to the shadow priest with everything as soon as we get cc onto the druid so he can't get any hots out. Basically just garg crows rapid fire and just go fucking ham as hell into the shadow priest. You can either start your cc chain with wyvern>trap or asphix>wyvern. I've got a couple vods of the match up here as well for you to watch how we play it out: http://www.twitch.tv...poo69/c/4539688
Vs Beastcleave: If they have a hpriest healer, you will train the enhance shaman as hard as you possibly can with everything into that priest. It's a rough match up and straight forward but you just need to go as aggro as possible. If they have a monk healer, type /afk, you will never ever ever ever win if they slightly know what they are doig. Hunter is the best target vs monk variant, but it's just incredibly hard for you to get a kill. Monk beast is one of your absolute counters are far as cleaves go.
LSD: You need to train the Ele shaman into the ground. Get fears off of cd, and you just need to play as aggressive as you can. Keep running at that ele and eventually you will score a kill against them. It can take a while, but you're going to have to be patient, and never sacrifice your offensive pressure. Go spirit bond as the hunter to help you against their rotting.
TSG: Somewhat annoying, but you can beat it as long as you have a priest healer. Make sure he gets fears on cd on the healer (Half of this comp is making sure you enable your priest to get fears as much as possible). Run at the warrior for days and hope for a kill. This match up is alright.
Anyways overall just the strengths of this comp is it's crazy offensive pressure, and it's weaknesses is that it's extremely linear and straightforward, you can't really change up your strategies too much because you are too limited in what you can do to win. If you ever lose your pressure and get forced defensive by another team, you will most likely lose the match. Go ham niggie.
P.S. If you have any more questions about this comp and match ups, feel free to ask me in this thread, on my arena junkies profile, or in game. Good luck ^^
