Apparently, experience does matter. I ran Aetherna through the Shadow Labyrinth early last week, and was incredibly frustrated - she died at least 4-5 times on trash mobs. At one point she managed to end up with a dozen mobs, including a couple of extra-tough Malicious Instructors, all trying to gnaw her face off.
Last night... she breezed right through. There were a couple of tight spots, but mana shield, evocation and invisibility (not to mention mirror image) saved the day. No patches, no in-game changes, no additional buffs. Just having run it once recently was enough to refresh the "Oh, yeah, this pull is a pain... wait a few seconds for mirror image, there we go, now kill!" bits of memory that I needed to have available.
Another 3 runs of Shadow Labyrinth should see Aeth at Exalted with the Lower City, which is wonderful. She hit revered with Ogri'la last night, based on the three dailies she's been doing. I've tried to do the event at Shar'tul's transporter a couple of times, but apparently it's bugged... when you get to phase 2, mobs show as friendly, so you can't actually complete the even and go on to phase 3. Bummer.
And now, for Music Monday... here's a wonderful lady, Karan Casey, singing a very bittersweet song about young men going off to war. She's accompanied by James Taylor, who's voice adds a nice element to the song. I'd say this is more of a "WotLK" theme song, though; I'll have to think about what an appropriate Cataclysm tune would be.
