Alright so theirs a "leak" going around about 90-100 levels. So this got me to thinking.
If we're leveling 90-100, what if the expansion after that isnt a leveling expansion, but a war expansion?
Example, World of Warcraft : The dark Below
Aftwards,
World of Warcraft : Reign of the legion (Fake example)
This time in this expansion we're fighting off the legion. So we're not leveling, but this is a full out lore expansion. No leveling, just storyline of the legion. New dungeons, raids , scenarios, lands of course, but theyre all level 100.
