I know that IA is basically a reskinned version of Descent, and I'm wondering to what extent we can look to Descent's development in predicting the future of IA.
Are there any concepts from Descent that have yet to make their way over to IA? What about heroes? I'm willing to bet there is a Barbarian type hero who has abilities pretty similar to Gaarkhan, and a Healer type that's pretty similar to MHD-19, and a ranger or wizard that's pretty similar to Mak. What are the other types that have been covered, and what other heroes does Descent have that don't have an IA counterpart?
