Give some feedback on what class you are going to be testing and playing during beta or launch and why. If you've been watching the game closely, you should have an idea or some type of preferance as to what class you will be playing or atleast what faction (order or destruction) for beta and/or launch. For more detail, please add what mastery/talent tree/s you plan to go with also.
I plan to play a Disciple of Khaine or a Sorceror. I always like playing the evil factions whenever possible to see the sick and twisted ideas the game developers implamented. Secondly I always like being a damage dealer but also enjoy having the versatility to heal buff and keep my party members alive and well in battle. I never like the idea of being a paladin/warrior priest because it seems to "good" and defensive. I'd like to drain the life of my enemies as I rip them apart with my blades and empower myself with their essence or wield magic to crush and rip my enemies in two. (I really like the bad ass sorceress in the newer warhammer cinematic video)
Dark Elf Sorceress also looks mad:
