Lost experience at lvl 100?

I mean, it’s a shame that once you reach level 100 it no longer adds anything, no experience, no paragon. It could be done like in DIII, all the leftover experience goes to the paragon to the class.
And the same with glyphs: once you have taken ‘all’ glyphs to level 21, the glyph experience is lost.

What happened to console discussion?
