Please, get rid of Glyph of Innervate.
Druid base mana at level 80 is 3496 mana.
45% of that is 1573.2 mana.
If you use Innervate on every cooldown, 180 seconds, this nets you a absolute maximum gain of 8.74 MP5.
That glyph is a complete waste, you'd get more mana regen out of a single gem (the gem Lustrous Majestic Zircon gains 10 MP5). This bonus is too insignificant to justify using a major glyph.
One part of the reason haste is so valuable in calculations is because they typically account for using Glyph of Rapid Rejuvenation. This glyph significantly increases the value of haste.
