Some of those glyphs don't look correct. Colossus Smash is a major. Hamstring doesn't do that anymore. Shield Wall provides 60% damage reduction but on a longer cooldown. That's just off the top of my head.
Prime glyphs aren't going to be exciting in a "change up your rotation" style. We want primes to be unambiguous dps (etc.) increases so we figured they might as well be easy to understand rather than something so convoluted that everyone would just go to a fansite to see which 3 to pick.
The majors are more interesting, because they are either not dps increases at all, or dps increases in ways that are tricky to math out. We think players will debate and geek out more about which majors to use, and with the new glyph design, swapping them out once in awhile isn't very painful.
Minors are basically convenience or fun.
We don't want glyphs to change rotations. We feel that was a mistake in LK. Talents should affect your rotations, and glyphs should just provide a little bit of customization and power. We fixed some class problems with glyphs in LK, which was an easy solution to do at the time, but now is the time to undo all of that and let the classes stand on their own without the glyphs.
