In vSL-2.6.11 the Firelands Raid shows up as being in the Borean Tundra zone of Northrend (but the provided coordinates are correctly for Mount Hyjal).

This is mostly intended as there are Legendary quests which are related to Firelands and take place in Borean Tundra.

At some point though this will probably be revised and ONLY the quests which take place in this zone will be visible in the zone, but it was designed a long time ago and could be improved in time.

I'm removing the maps tag of the entire questline, and added a note that the respective quests need proper coordinates added, and the proper quests will then show in the proper zones, without the entire quest chain being plastered into multiples zones without context.
