Testing Innervate on the PTR, May, 4th.

Anticipated result:
Innervate with glyph should yield 540% of base mana. Base mana = 3496, thus;
5.4 * 3496 = 18,878.4

Innervate without glyph should yield:
4.5 * 3496 = 15,732 (for reference only, regeneration without glyph not done in this test)

Method:
I activate my primary talents, setting my mana to 0. I then cast innervate on myself, at the end of the duration of Innervate I take a screen shot.

Potential error:
There are several possible errors that can come from this method. One comes from the delay of innervate completing and my reaction to take the screen shot. This margin is minimal. Also, incidental mana regeneration during the duration of innervate means the numbers yielded are not the actual numbers that innervate regenerated; actual mana regenerated from innervate is less than the reported results below.

Actual Results:
With my Raiding gear equipped I regenerated 11,465 (18,878.4 expected) mana during the 20 seconds that innervate was on me.

Conclusion
Change to Innervate is not yet implemented. Test to prove this conclusion:

With the PTR client and the Live client open, I tested innervate under 4 situations. I equipped my PVP gear on the PTR and conducted the previously explained method. I then repeated this with the exact same gear on the Live server. I repeated this for my Raiding gear. The results:

PTR PVP Gear: 8168 Mana Regenerated
Live PVP Gear: 8011 Mana Regenerated

PTR Raiding Gear: 11465 Mana Regenerated
Live Raiding Gear: 11384 Mana Regenerated

The error above is within acceptable margin to conclude that the reported change to Innervate has not yet been implemented on the PTR.

Edit: I forgot to mention that the Screen Shots can be made available if requested.
