Voici ce que j'ai trouvé. pour ceux qui lisent l'anglais, ils ont les détails. Pour les autres :
- le DOT à 750 dégats toutes les 3 s ne peut pas etre dispell sauf pour les voleurs
- le dragon a un debuff qui retire les buffs des attaquants. Les mages 70 peuvent le lui retirer (j'ai pas compris comment)
- ET SURTOUT : si on rate la dernière étape, Thrall repop à coté d'Aretha dans l'auberge et on peut reprendre la quete. Par contre, c'est Thrall qui doit tuer le dragon, sinon in ne meurt pas. C'était pas un bug. Je pense que c'est pareil pour Thrall : c'est le second boss qui doit le tuer, sinon il ne meurt pas. Comme on a tué le boss avant les adds (et wipé ensuite), thrall peut tenir la soigneuse indéfiniment.
C'est pas forcément très clair pour ceux qui n'ont pas fait l'instance, mais pour les 5 d'hier soir, c'est lumineux (si, si)
General Info
* Level (Normal): 68 Elite
* Level (Heroic): ?
* Type: Dragonkin
The Epoch Hunter appears after you have escorted Thrall to Tarren Mill and found Taretha inside the inn.
[edit]
Abilities
Sand Breath - a casted breath which does damage to all in front of him. Melee or people close-by should move away when they see him casting.
Impending Doom - a DoT which does 750 damage every 3 seconds. It is not dispellable, and should be healed. However, it can be removed with Rogues Cloak of Shadows.
Knockback - a knockback.
Disrupt Magic - an aura which dispels buffs off of the players with each tick. If you are fortunate enough to have a level 70 mage in your group this aura can be stolen. This will prevent all of your nice buffs from being dispelled. You will however have to resteal this buff every ten seconds or so as it has a short duration.

Tactics
This is a longer fight than any of the other bosses in this encounter, so healing and mana users be ready. (be sure Evocation, Innervate, and Shadowfiend are off cooldown)
This fight starts with the Epoch Hunter coming from above. He keeps flying over Tarren Mill, but he is not attackable. He will send three waves of adds:
* The first one spawns at the west side of Tarren Mill (by the epoch hunter), and has two melee dragons and one caster. The caster should be taken out quickly.
* The second wave is the same as the first, and spawns to the south of Tarren Mill.
* The final wave will come from the west like the first, and has three melee dragons and one caster.
* Finally, the Epoch Hunter comes down.
Seeing as he has a nasty knockback, he's best to be tanked near the northwestern small house of Tarren Mill, under the outside roof of it. This way, the tank can grab aggro quickly again. Watch out for his breath, and healers should watch out for his DoT. After he is dead, Old Hillsbrad Foothills will do its last little cinematic.
For the entire instance Thrall can die twice, and the encounter can be reset, either from the Keep, outside Tarren Mill, or beside Taretha depending on how far through you are. If you wipe on this boss, he appears beside Taretha after a short period of time.
Important note! If Thrall does die three times and you reached the boss, the boss will be found hovering in the center of town. Thrall is dead. You can engage the boss and fight as normal, but since Thrall must strike the killing blow, the boss will persist indefinitely at 1% health. He will also taunt you, saying that Thrall is dead and 'you lose'. Save your strength (and your repair bill) and reset the instance after your second failure.
