We tried Mount Hyjal for the first time the other day. I've never been there so it was fun to be able to see something new in the game.
We prepared quite well and Rage Winterchill went down on first attempt. Anetheron was more trouble tho. The waves of mobs were never any trouble and neither was the boss himself. The real issue were the infernals he spawned. Took some tries before people fully understood the concept of "run to the tank -before- the infernal lands". Took us four tries to get it right.
Good thing about it was that epics dropped on all the tries before success which made the failing attempts more lucrative loot-wise than an immediate success had been. Two recipes and some back and axe dropped if I remember correctly. But boy those fights were fun!
Long till we go there again.
Finally got my epic flying machine on my hunter, so now I've got a decent herb/mote gatherer. Weee!
