Breakfast Topic: What was your favorite expansion?

With the Warlords of Draenor expansion just announced, it seems like a good time to look back on expansions past. And while we've played through them all together, everyone has a favorite expansion. Perhaps you prefer to play a draenai from The Burning Crusade, maybe you enjoyed battling Arthas in Wrath of the Lich King, or perhaps playing through one expansion has particularly good memories -- but whatever your reason, one expansion probably stands out against the rest. So tell us, readers: what's your favorite WoW expansion?
