Diving straight back into Hyjal tonight resulted in two fresh kills, each taking two pulls. The only real thing to say about Anetheron is F you, Jaina, dirty poly-breaking wench. At least Thrall's Chain Lightning doesn't break shackles nearly as often.
That aside, the trash wasn't much different than Rage's. Really though, the fight is very straight forward, difficulty placing equivalent to Rage Winterchill. Partial positioning, partial healing, partial don't-sucking.
Kaz'rogal felt like a proper step up in progression. The Horde Encampment is much more difficult to utilize than the Human one, but the trash proved another level of spacial awareness when mobs spawned in the air and out in BFE. Kaz'rogal himself is, for my taste, too similar to Kazzak. The faux enrage system is also annoying for casters at 2 pots per pull, but we'll live.
Moral of the story: Thrall > Jaina, Horde > Faux Alliance, and Chain Lightning > Pyroblast.
