Hey, just wanted to throw up a quick post about the Lovely Charm Bracelets that people are so eager to get for the meta achievement. As Markco pointed out, you can farm for them in Ulduar. However, what if you've never been to Ulduar, or don't want to go? I think it requires a raid group to do it as well...
Well, since I just recently spent a LOT of time in Icecrown for Loremaster, I immediately thought of 2 quests that I did a few times. Riding the Wavelength, and Total Ohmage. Since you don't have to loot the mobs to get the Lovely Charms for the Bracelet, ANY quest or action that you do that allows you to kill mobs near your level in a quick fashion will suffice. And dropping bombs on all those mobs in the Bombardment netted me about 40 charms in 3-4 minutes.
This is especially helpful if you're looking to get those dailies done for lower level alts, and don't have the time to go out and kill with each of them.
