It only recently occurred to me why I dislike (some of) the DA:I characters. They are just too ordinary. In order for them to be interesting to me they have to be in some exceptional circumstance, and it is not enough for them just to be members of the inquisition. I mean they have to have some sort of exceptional personal circumstance.
This was evident in the ME2 characters for example. Mordin had a huge guilt complex about the genophage; Thane was dying and wanted to reconcile with his son; Jack had been abused and experimented on, etc. In fact the boring characters, like Jacob, were the ones who weren't extraordinary.
DA:I had a cast of Jacobs, except for a few notable exceptions. Cole for example was a great character because of what he was, and his attempts to come to terms with it. In principle Solas should have been interesting but wasn't because his exceptional nature only came out at the end. But everyone else was actually pretty unexceptional and frankly dull. Vivienne for example was only distinguished by her link to the circle and the Orleasian court, but otherwise had nothing to distinguish herself. Similarly for Dorian, and Cassandra and Josephine. Iron Bull could have been more interesting but his exceptional nature (i.e. a Qunari) was never really explored. Blackwall we quite interesting but also intensely annoying for being such a self centred whiner.
If characters are not exceptional I would rather spend my time getting to know real unexceptional people.
