What's the purpose of any profession?  A few gimmicks, a few widely-useful items, and a decent way to generate cash.

I thought that WOTLK is supposed to eliminate that.  God, if they make drums ineffective, than what purpose is there to leatherworking?  A pattern that costs 20k to buy and 3k in mats?

I was just comparing it to the other shots.  I think i also chugeed a haste potion at around 50% or so.  I always forget about them haste potions.  Now if only we could get judge, ora, and dragon to reroll lw up to 350 to use drums, we'd all be set.
