Below is an interesting thread about someone mining the Armory to get semi accurate data on 31 and 41 pt talent specs. The person did it to try and prove that everyone hates the Holy priests 31 and 41 pt talents, but there is data for all trees. ~4600 characters were scanned, ~1500 of them being priests.

I'm not sure this is what blizzard had in mind when they released the armory.. The two talents are horrible, and having data to prove that the general community doesn't like them is good.
But I'm not sure data that proves "40% of holy priests that have 30 pts in Holy don't choose Lightwell" will actually do anything.

Still this forum is more of a Data/Numbers community, and I found it interesting, thought others might too.

Thanks.. Didn't realize it.
