Really, before 50, it's debateable to which is "faster." After 50, shadow is still considered the "fastest" spec.
To clear things up about a
Glyph of Inner and PW:S, the glyph doesn't increase your absorption of your shield, but it
does increase your total armor, which is caluated in the amount absorbed by your shield.
The reason some people consider holy fastest for leveling, because early on smite is your most potent spell w/o a CD and holy gets
Divine Fury in levels 15-19. Later, in levels 35-36, you get
SoL, complete an lolsmite build.
At level 40, shadow gets
Shadowform, and at level 50, shadow gets
Vampiric Touch.
However, I've always agreed that
Meditation is vital for leveling at higher levels (and still very useful at lower levels). When I was leveling 70-80, I purposefully kept Meditation in my build, even though it ment I didn't get the full use of my shadow talents until later.
