I'm really bad at remembering to take screenshots (and I take bad screenshots when I do -- see below for examples). Anyway, I forgot to take one of Al'ar, but I figure a picture of the toy we got from him/her/it, which is probably the single coolest model I've seen in the game so far, will suffice:

The feathery talons wave back and forth, and the whole thing glows. The fact that it's a pretty badass rogue mainhand doesn't hurt either.
Anyway, fun fight, and as with Vashj, while I definitely don't regret putting these fights off until 2.1, I do feel for the guilds that struggled through the untuned versions. Al'ar right now is a lot like Hydross in terms of feel and difficulty, which is probably about right given where the fight falls. It's fun, though, and the changes prevent it from dragging on for so long that it becomes tedious.
Looking forward to checking out Kael'Thas on Monday!
