DRUMS OF THE WILD
As the servers opened their patch-day doors, little leatherworkers rushed to their trainers' stores. "A new pattern! A new pattern!" they cheered and cried, but then the druids suddenly rolled their eyes:
- 8x Heavy Borean Leather + 8x Icy Dragonscale = 50 charges of MotW
- 50x Wild Spineleaf = 50 charges of MotW
- 50x Wild Spineleaf in the hands of a druid who, like almost all of them, specced into IMotW = 50 charges of a better MotW
Don't use drums to buff MotW unless you're out of druids. Or, somehow, your druid didn't spec iMotW. Which is nearly never. These drums will be useful only in instances/raids that are lacking a druid.
DRUMS OF FORGOTTEN KINGS
"Ah!" but the leatherworkers said, "We learned this new pattern, too! See these drums here, look what they can do!" Peering at these drums, the druids now did ooo and ahh, for this was something new: a stat buff increase of 8%! A feral nearly wet his shoes. But along came a paladin, who leaned in close, then he sat back and laughed:
- 8x Heavy Borean Leather + 8x Jormungar Scale = 50 charges of 8% stat increase to whole raid
- 50x Symbol of Kings = 50 charges of Greater Blessing of Kings (10%) on a single class
Don't use drums to buff Kings unless you're out of paladins who are free to cast Kings. This may be useful in 5-man heroics, or in rare raids that are pally-less, or in cases where your pallies may be needed to buff other things (ie might/wis) and you want Kings along with it!
DRUMS OF PANIC & SPEED
As the leatherworkers sat on the stoop and did cry, along came an elder druid, battle-worn, but with pride. "Have no fear, fellow crafters," she now did say, "There is still yet a drum with some use; and you can learn it this very day! Go to the dragons who watch the sands of time, and earn their favor quickly with all the quests of the line. Once you have gained honor in their golden eyes, you will have a Drum of Panic as your musical prize! These unearthly beats may be 10 levels old, but even at 80, your foes will flee, should you strike bold!"
...okay, I'm done attempting to rhyhm now. Drums of Panic (Edit: and Drums of Speed!) from TBC were not nerfed like the other TBC drums, and are useable in level 80 content and PvP. They are, however, only useable by leatherworkers. They save my tail in heroic faction champs in ToC. :)
Oh, and wtb drums of bloodlust.
