Since I have started to visit the Arena regulary, i have thought about classes and their threat.
Which leaded to a boost of effeciency in our Team.
In cooperation with my teammates we listed the highest threat target in following order:
Top 1 Threattargets:[/u]
ShadowPriest (ManaBurn, soft target goes down pretty quick even with two Healer in the opposing Team)
Mage (Pyro specced, huge burst Damge, soft target)
Shaman (Never underestimate a Shaman in what ever built, see one kill one)
Group 2:Warlocks (Only a top threat if you have Player in your Team when nobody can propperly dispell their dots)
Priests ( Play a Priest correct and he will make his way to the top 1 threat, imba group healing, very i efficient)
Paladin (Those Tin-Cans are build do absorb a nice amount of Damage, but I´ve never seen a Pally in full plate so far in the Arena [hence known Pallys ] best tactic to reduce their Threat, bring em to bubble themself, if they bubble nuke another target and get back to the Pally afterwards)
Druids (their threat varys, MeleeDps are pretty seldom and can be a be put in Group 3. Moonkins, due to their cuteness factor i like to kill em at last, but since they can deliver a hard amount of damage, they don´t deserve this right, same for Restro Druids)
Group 3:Rogues (Can be a pain, but their damage can be Outhealed, or you nuke em in between, what i love to do as DPS Warrior ^^)
Warrior (See a Protwarri, blow him a kiss and kill his Group, see a Mortal-Strike Warrior, CC him but don´t touch him, a Warrior who suffers from Damage is even more dangerous, Fury-Warriors tend to wear Leather, so you can kill em inbetween, but don´t get fooled by them CC is always an Option)
Communication is essential, like DaffyD said.
Try to use ORA2 or Ct_Raid establish a MT and focus your fire, the player with the most overview should announce the targets concerning their estimated threat towards your group.
Get yourself the
Arena Master Addon.
What AM does: It shows you the classes of the opposing team, they can be announced that way and ppl can better predict what they face.
One other thing: If you feel comfortable enough, rush, put mayor pressure on them, or do it the other way arround, stay at your place secure it, protect you and don´t even move, let them get agitated, they´ll come fore sure And than they´ll make misttakes and you can divide them easy
My thoughts about the Arena.
Btw:
I´d say take down their Healers first, but we experienced that isn´t allways the best thing do, while you try to focus on a healer their dps will surly try to take down yours.
Again learning by dowing, stick to Daffyd post and you´ll raise constantly
