The inquisitor is a very versatile class. Through advanced class and skill selection, the player can mold this class to fill any of the traditional roles of characters in massively multiplayer games.
The biggest thing I took away from that interview is the fact that it seems like each class will be able to build themselves into any of the classic roles. Bioware says as much a couple time in that interview. This is a development I will have to get my head around, I keep thinking that BH and SW will be the tanks, but this interview says the SI may be one as well.
I dont see the SI tank being better than the BH tank, but what do I know?
