I think there are really two types of people when it comes to liking the IQ or not. Those who LOVE to RP their characters like in MMO games and those who would rather the game itself through dialog have their characters fleshed out. Those who love the RP/MMO approach are more prone to be satisfied with the IQ while the latter is more prone to not like the IQ's personality that much.
There's also a third type of people: those who love to RP their character but think that given the high status and respect, the main char's responses were generally too meek for it. I felt no drive, no sense of purpose in her, such a passive personality didn't fit a leader of an organization.
And I really don't care for backgrounds, origins, and histories. I just don't like that responses are so sheepish for a leader who should carry some authority while speaking.
In the beginning of the game Josephine said that Cassandra could be the leader of Inquisition, but alas, she lacks charisma for it. Excuse me, I thought, Cassandra is a lot more charismatic than our char! She's actually very driven and noble, how can you even compare that to the blandness and passiveness of ours.
Again, I do not mind the diversity of dialogue reactions, it just feels jarring to me that no matter what I choose, main char is being meek and sheepish instead of a leader. It prevents me from RPing my char, because her responses clash with a personality of a leader that I'm desperately trying to imagine.
