Is the Direbrew battle youre referring to the boss fight one in BRD that you take the mole machine to get to or another? Im assuming the latter as any 5-man PUG can take out the boss (Im hoping you know of another Direbrew fight I may have missed).
I really like the achievments now. Just last night I got "Damage Control" for causing at least 300,000 damage in a single BG. One of my favorite new tricks since they gave Blastwave a knockback is during an AV battle, when all the alliance group up on the bridge in front of their castle, is to run into a pile of them, fire off Blastwave and watch them all sail over the ledge to a big drop. Man, do I love being a mage.
