There are a few very powerful teams in Wrath of the Lich King arena. The top of the list is Frost Mage which has incredible burst damage and unreal crowd control.
Affliction Lock / Resto Shaman is another very strong team composition. Despite losing Feral Charge, it still has amazing sustainability with Innervate and can easily shred Clothies with Improved Barkskin.
Shaman
When you think of a shaman, you may imagine someone in a yurt in Central Asia drumming and chanting or a Native American elder leading a peyote ceremony. But there is much more to a shaman than those roles alone. These spiritually functional people are found all over the world, performing a variety of rituals and ceremonies to serve their communities.
In Wrath, Elemental Shamans picked up a lot of new totems and buffs that make them one of the most well-rounded 3v3 Arena compositions. With Hex and roots from Storm, Earth and Fire, absorb shields from Glyph of Stoneclaw Totem, and powerful cleave damage from Torrent of Flame and Wind Shear, this is an extremely dangerous combo to face.
Shadow Priests also picked up some significant new tools to improve their play in Arena. Dispersion gives them a hard crowd control, Psychic Horror is a great debuff, and improved Devouring Plague allows them to spam it for large burst damage in kill windows.
Ret Paladin
Since the changes in Wrath, Ret Paladins are now a force to be reckoned with. They're incredibly strong in 2v2 arena and have excellent burst with their major cooldowns and Divine Storm. They also have high cc utility with Hand of Reckoning, Sanctity Aura and Sacred Cleansing.If the online users make use of this website online, they can get information about wotlk classic gold.
In 3v3 arena, Ret Paladins pair amazingly well with hunters and rogues and pump with mages. With their new talents like hand-up protection, blessing of freedom and the amazing art of war procs, they're one of the strongest comps in Wrath.
In addition, Ret Paladins have a strong burst window with Hammer of Justice and Strangulate, along with their defensive cooldowns like Expurgation and Templar's Verdict. This makes them very powerful early on in the expansion.
Warlock
The Warlock is a very interesting class. Its one of the most powerful classes in terms of duelling, has a great defensive toolkit with things like Icebound Fortitude and Anti-Magic Shell and an impressive offensive capability in Summon Gargoyle. Its a good option for the solo player and also has plenty of utility for 3v3 play.
The only issue with this class is that it has some problems against compositions that have a lot of ranged interrupts and a priest with Mass Dispel. This team can still be a threat, but it needs to keep the enemy CC chained up in order to do damage.
Affliction Warlocks are excellent for this comp, as they have a ton of damage and very good control with things like Hex and Mind Sear. This allows them to one shot enemies and also deal massive burst damage to their opponents. This is a very strong combo, especially in the earlier seasons of Wrath when Priests can be very squishy.
Warlord
The Scourge is on the verge of unstoppable destruction, and only Bolvar Fordragon can stop it. With the Alliance king dead, the warlord takes his place and vows to keep the undead under control in Northrend.
Warlocks pick up a truck load of new toys in Wrath, including a solid ranged CC with Wind Shear and hex plus amazing crowd control in the form of Polymorph and Bloodlust. They also now have an extremely strong burst with Lava Burst and Lightning Overload. In the hands of an experienced player, a warlock can easily win an arena match if they have the right comp.
