No need to dig through those complex guides anymore. FatbossTV's one-minute summary of the seven bosses and their tactics inside Warlords of Draenor's first raid, Highmaul, is all you need to drop into the group chat before the fights. I wish it was that easy.
Probably not a good idea to share this when you're running with strangers in an LFR group. The part with failing at the third boss, Tectus, is just too real.
