You can laugh. But I've seen people with 'perfect' bodies walk around like glorified zombies, and people that could hardly count their looks as assets have their pick of partners because they were outgoing, funny, had a nice smile, were really sweet, or were great conversationalists.
IMO, it's personality that wins over beauty any day of the week, and twice on Sundays.
To link this to the topic, some of my Inquisitors may not end up liking Cassandra's personality, but there's no way anybody can say she doesn't have one. That's the best part about Bioware characters is that they have interesting personalities, with a few exceptions(*cough* Jacob *cough*). I could care less how Cassandra looks in the game. What's more important is how her voice actress delivers her lines, how the animators make her move and react in cutscenes, and how the writers write her character and her dialogue.
