Change to innervate? ZOMG OH NO!
That was my first reaction. I, apparantly, fear change. However, after that brief moment of panic, I sat down to figure out just how much mana we're getting from this skill.
Since it was changed to grant 450% base mana, and a level 80 Druid has 3496 base mana, Innervate should always return 15732 mana by itself. My unbuffed mana pool is about 16551. This would seem an improvement over the other innervate just upon personal return, not to mention it no longer relying upon your target having a large amount of Spirit to function if you're going to hand it out to that silly oom Paladin.
Glyph of Innervate changed a bit, as well. Now it returns 90% of your base mana to yourself if you cast it upon someone else, or combines the 90% with the 450% when cast upon yourself. This means a return of 3146.4 mana to yourself (at 80) when you cast it on someone else, or a total return of 18878.4 mana if cast upon yourself.
I'm definitely liking this.
