Aside from the 2 new char classes and more skills for existing classes GW is also adding a new Hero type of henchmen
They seem pretty cool, you pick em up doing quests kinda like you would with normal henchmen except you get to pick their 2nd profession AND distribute everything... from skills, equipment to even their attributes.
Thats pretty sweet
Yeah the Heros idea will help people who dont like spending hours forming a good party. Since they can set up decent builds, obviousely they arent as good as real players (well actually 90% of the time they are far better but thats beside the point....) however it is better than being stuck with charge as the elite on your warrior
