Simple Leveling Overhaul for next expac

Max level reduced to 60.

Levels 1-40 take about as long as the current 1-60
Levels 40-55 take one “past expansion”. Basically play through your choice of one of the following; Outland, Northrend, Cata zones, etc to reach lvl 55.
Levels 55-60 will be the new expacs content.

Leveling “difficulty” remains approximately the same.

No level squish will be simple. Cutting the levels in half would require a complete revamping and re-balancing of all the old world.
