Little necri-threading here but I did my first one the first night I hit 90 on 3 of my toons. Fly to the Temple of the White Wolf, get the quest and do Arena of Annihilation for the 450 weapon. I did have some very minor issues in here with the walls of fire on my 2 x enhancement shaman and 1 x boomkin. I ended up finishing this one with the boomkin healing and doing 80% of the boss with fire by herself due to enahncemebts being stupid.

so easy way to get 450 weapon to help work the grind.
