Other interesting tidbits:
McQuaid says players will have to formulate tactics and strategies of their own to succeed, and will have to bring the right equipment, abilities, and items for specific encounters. "You're also not going to have 47 clickies up on the screen," he says.

McQuaid says, although the exact details of what this content would entail were still being discussed at the time of the interview. In line with that, leveling could end up focusing on more "horizontal" content than "vertical," so (in McQuaid's words) you end up with as much content in 20 levels as you normally would in 50.
Possible level cap of 20.
