Taken from our
Class Section:
Expected to be a fanatical fighter seeking out truth above all else, the Inquisitor will certainly be a force to be reckoned with. This fighter may often be found on the field of battle probing the minds of their opponents, looking for weaknesses that can be exploited for the good of their group. For that reason, they are typically highly perceptive and often times even know what their opponents are going to do before their opponents do it.
From Eldiroth on the OVF:
Actually, Inquisitors simply run around bursting through doors yelling "Noooobody expects the Vanguard Inquisition!"
... okay that last one isn't serious, but hey
We don't know too much other'n the name. They're tanks, are good against casters, and are rumored to use psionics. However, according to a developer from Fanguard, they recently went for a total revamp and as a result may not make it in for launch.
