The name of the game in raiding is learning what makes a boss tick and using it against them. Since the beginning of PvE there have been people kind enough to figure out the fights and let the rest of us know what to do. You can find strat guides all over the interwebs, including sites like Bosskillers and WoWWiki, plus more.
And while those are great resources that we've used time and time again to defeat our foes, the wall after wall of text has been hard to digest for some of our TLDR (Too Long Didn't Read) members. What if there was an easier and more entertaining way?
Enter Akaineko (Bazlek) and Scorpio_Angel (Zhain) on WoW Ladies and their illustrated boss strats for Leotheras, Lady Vash (Phases 1, 2, and 3), and just out yesterday... dun dun DUN: Illidan 1, 2, and 3. I made Zhain pinky swear that someday they'll do Kael as well.
But they're seriously killer guides and the commentary/art takes learning boss strats to a whole new level.
[Thanks to Jaxson_Bateman for pointing out the additional Illidan parts!]
