I'm guessing they'll make a ranged class with the ability to heal since the previous hero class was a melee class with the ability to tank.
I'm kinda hoping it's another class that can make use of bows/guns. I just feel like it's a little absurd that there's a whole weapon type solely devoted to one class. I suppose throwing is the same, but it's not like anyone really uses their throwing weapons outside of pvp. :P
And I really like the idea of them introducing a new healing class that isn't a normal caster. Give me something that will fight in order to heal. Like let me channel the damage I could do to the boss as healing to others instead. Anything to make the differences between the healers be more than just armor type and relative stupidity of their masteries.
Anyways, you all are horrible, @#%^ed up people
Never underestimate the healing power of a massive dong.
