Comments
Note: the stats mentioned are for normal mode. On heroic, the Corrupted Ancient is now a 20/400 which spawns a 6/6 treant when damaged, improving by +2/+2 every subsequent instance of damage.
It has three abilities:
You therefore want to avoid AoE and multiple attacks (combo'ed Baron Geddon or Guff Runetotem, for example), otherwise you'll just get overwhelmed by the treants directly and indirectly.
The most consistent strategy is to bring buffers that don't attack, and consistent healing or taunts. Just build up your team slowly, heal the damage you take, and make a few short bursts of damage when the time is right. Personally, I like Cariel Roame (with Tome of Judgement or Light) + Tirion Fordring (with King's Helm), and either Brightwing (for the mass healing) or Tamsin Roame (for the healing denial + recurrent taunters).
