I'm of the opinion that the game is in need of a level squish. There just isn't enough character progress when leveling up to warrant 110+ levels of buildup. Going 15 levels between changes to your character is rather silly. I'm sure they're still basing things around the test grouped data they have that says people need the 'ding' every so often, but their game design has long since left that pacing behind. Every level needs something more than just base stat increases, or it's arbitrary bullshit.
The zone scaling has opened up things to allow them to just toss all the old shit into one large pre-current-expansion level group, hack the actual number of levels, and let people pick and choose what they do while leveling. I don't know what number of levels would work, but I'd be fine with something like 50 levels of pre-current-expansion content with talents, skills, and an artifact-like progression system providing new things for each level and then your standard 10 levels for the new stuff. Then just move down the expansion content into the large pool when the next one comes out.
