Still if you insist on getting your achievements here are a couple of thoughts for hunters.
- Get pathfinding. Ten percent increased mount speed is a godsend here.
- When stealing the flames from the capital cities I found that popping deterrence bought me enough time to click on the bonfire and collect the quest item. The only resistance I met was in Orgrimmar and Thunder Bluff, where I leaped off Spirit Rise to a glorious death (man I miss engineering). The other two cities were easy. Still though deterrence made a big difference for me.
Oh, one other note about the holiday. You can no longer buy the Midsummer outfit (which is needed for an achievement) and return it for a refund. That means if you want any of the pets you'll probably need to do the dailies each day and visit every stinking fire in the game.
