-World of Warcraft Arena Tips -
Work on getting down their defensive cooldowns, then kill something in a HoJ -> Death Coil -> Counterspell. If you can't kill someone in that, then you'll have to play the mana game. ALWAYS keep everyone dotted up; full dots on everyone burns through a healers mana quicker than a Mana Drain. If there's another Lock or Hunter, go hard on their pet while keeping everyone else dotted up, the healer will be forced to dump mana into healing the pet. Also, be sure to Mana Drain caster dps if their healer is pillar humping, it's really easy to oom Spriests, Mages, & Ele Shamans & it forces them to play really defensively. Against Resto Shamans, never have your pet on them, pump out your damage on his partner to force to come out from behind the pillar, then get a Mana Drain off. With Druids, be sure to look out for whenever he Roots your pet & get a dispel on him to stay on the Druid. Also, look for opportunities where he's out in the open at <80% health with no HoT's up, you can most likely get a kill there. Toggle auto cast on Devour Magic on healers until you've cleaned them of buffs, so it'll be much easier to Dispel Innervate, Divine Plea, etc. With Priests, Fear the pet when it comes out, and get ready to interrupt his Hymn. You stop those two & it's GG for you guys. Also against Priests, be sure to have a good distance between you & your partner to avoid both getting caught in a Fear, which usually results in Mana Burns going off.
Also, have your Pally call out to you whenever he's going to Plea, so you can have peels ready to avoid it getting dispelled, you'll come to learn that Dispels are your worst nightmare in this comp.
