She was humorous and such a world wise character and I loved that.
This.
I enjoyed taking the ladies out in Da2. Aveline, Isabela and Merrill made for some good banter.
Also this. Aside from Varric, the dudes in DA2 were kind of boring. Rather, they should by all means have been interesting, but they just weren't. Anders was the most interesting one due to his bond with Justice, but that never came up outside of plot quests.
Edit: Also she wasn't hung up on other peoples opinions on her, she knew who she was and that was all she needed. Didn't care if someone didn't approve or not. Many people could learn from that in my opinion. It is probably what I find Cassandra's biggest flaw, she can be hung up a bit on how people perceive her, if she was in the right for forming the inquisition, that they would think less of her for enjoying swords and shields. Screw that, embrace who you are and enjoy it, do not be ashamed of what you love.
Dunno. Cassandra never struck me as someone who would care too much about what other people thought of her. She knows her reputation and she knows her abilities. She might consider someone else's opinion for a minute or two, then get back to work and never mention it again.
