I’m not sure if this is the right forum for this, but I’ve noticed what seems to be a bug. The achievement “The Warlord of Draenor” grants the “Alliance Champion” title, while the “Legionnaire” achievement gives you the “Horde Champion” title.
As a WoW player, I find this a bit confusing and inaccurate; it feels like it should be the other way around. “The Warlord of Draenor” clearly references the history of orcs and should be associated with the Horde, while “Legionnaire” is a rank from Stormwind and should belong to the Alliance. It’s a small detail, but I believe it should be corrected!
