With only a week's worth of stories and no hard data, I wanted to ask whether other people's opinions. From the little research I've been able to do, I've seen support that a Holy Paladin, a Holy/Discipline Priest and a non-Restoration Shaman core is the winning hand right now in the 5v5 bracket.

With this combination, your enemy will have a near impossible time of taking out your healing capacity with crowd control. With two possible sources of healing, focus-fire on any one healer isn't likely to go as fast as it needs to be an effective tactic. You have two sources of both offensive and defensive dispels. Finally, you have the Shaman's Heroism/Bloodlust which increases melee, ranged and casting speed by 30%.

The nature of the DPS varies. Clan Hex has fielded DPS in the form of a Warlock and an Ice Mage and had an Elo rating somewhere north of 1900. Other teams field dps involving Warriors and Rogues due to their healing debuffs and the greater advantage they can take from the aforementioned Heroism/Bloodlust.

World of Ming and the experience of the people who have posted there provide the support for this idea. As his site is currently down, I'll have to to provide links later.

So my question is, do you have any Arena experience to support or contradict this assertion? Have any of you seen any very successful teams (Elo > 1900) without this class compositions?
