I would really love to see how the new holy power works... however I didn't get a beta invite, so I'll have to rely on you to show me!
One thing I would like to test if I could would be Templar's Verdict vs. Inquisition for ret paladins. Would Inquisition be a bigger damage boost for ret over the duration of the buff than the Templar's Verdict instant strike? If that would be the case, then that would open up another choice between having a button to press for burst damage and having one just for extra damage that you know you can use because you're on the same target for some time.
I can already see the choice prot would make, being more survivability via holy shield being extended, or more threat through inquisition. This I love... as I just love choices. Holy on the other hand just has one choice for healing... Word of Glory. I'm wondering if they could give holy a choice, maybe a mana regen skill that uses holy power. That way they could choose between throughput or regen. Not sure that would work, as Word of Glory is already 0 mana cost... but that's just my mind running.
Also... I hear Peter Jackson is looking for some actors for the upcoming Hobbit movie. Maybe you have a shot?
