The Worlds of Azeroth, Outland, and Draenor

The problem with the MMORPG version of World of Warcraft's world is that it's too small. Both the continent of Kalimdor and the continent of Azeroth are about the size of Oahu island in the Hawaiian archipelago. The capital cities are about as big as your neighborhood at least, with Stormwind being the largest, with Silvermoon and Orgrimmar competing for the second largest.

This RPG treatment fully assumes that the World of Azeroth is much larger, about the size of Earth, and that both Kalimdor and Azeroth are the size of Europe (and because there aren't wandering typhoons that are powerful, its assumed that there is a continent the size of Asia on the other side of the world). This mades for a much more interesting world to adventure in.

Heroic Areas
Heroic areas are areas reserved for normal adventuring at levels 1-20. This includes parts of Northrend, where Arthas' expedition landed to defeat the Scourge of Lordaeron. Heroic adventures are those found in the Trisifal Glades, the Arathi Highlands, and other areas such as Desolace.

Mythic Campaign Areas
Mythic Areas are areas of high level adventuring, including Northrend and the Alternate Universe of Draenor. The ability to kill the Lich King Arthas Menethil is certainly a Mythic level quest, and requires Mythic level adventuring. The Draenor that the former Warchief Garrosh Hellscream went too is also a source of Mythic Level adventuring because it has the potential to alter time in the normal Material World.
