Books were bumped down from 75 to 90 it seems. The entire 90 tier got booted out of space, which is a welcome change since it gave devs a massive headache.
There's a crap ton of Spec specific talents this time around. Summon Inquisitor is probably going to be using the Tall demon with the long coat with it as the model, which is pretty good looking. (http://media.mmo-champion.com/images...-artwork-9.jpg)
I will have to wait for an official confirmation on the talents, cause a few overlap and some others are missing a talent. So far, it looks okay. Demonology got some sweet demonic summoning and instant cast love.
No sign of Demonic Servitude, so that shit is out of the window.
