The Battle for Mount Hyjal

Just a side note, if you try to fish in any of the water regions in the instance, you get the "there aren't any fish here" message.

I know this is an old raid, but some of us like to revisit and stomp all over them, so a few notes regarding spawns and such for others who are frustrated with this raid.

Alliance Camp. All mobs will spawn on the road beyond the front gates. No need to move from the gates, just stand there and AoE the waves down as they come. Speak to Jaina Proudmoor to get things moving.

Horde Camp. Some waves will include flying mobs that will pass over your position at the front gate. Finding them is a real PITA, unless you have a Hunter along. Turn on Track for undead and demons, and mount up to go collect them. If you are unable to find them (having no tracker), run around the camp until you find orcs killing something. As the camp is rather spread out, this can be time consuming. Speak to Thrall to get things moving.

Nordrassil. Find Archimonde on the north side of the world tree and burn him down. Killing him too fast is kinda pointless, as he will stay at 0% health for quite a while, casting and whatnot - he will eventually give up the ghost. Speak to Tyrande Whisperwind, sitting on the white tiger at the top of the hill above Nordrassil to get things moving. She will give you a clicky that slows your fall for a time, never had to use it myself.

Misc. Having a toon along with mining skills is handy, as there are a number of ancient gem veins scattered around the zone.

I had several soulbound tailoring patterns and jewelcraft designs drop, so there is added incentive for a tailor or jeweler to run this .

As others have noted, there seems to be no exit from the zone, other than a mage port, or hearthstone, or any other port methods you might have.

Correction, you'd have gotten it if you had anything that was an Archimonde exclusive drop, since you obviously had to kill him to get it.
