That is what makes her interesting, she was simply bland before this.
I disagree, she was more generic than bland, also its a mute point as making her all jaded doesn't make her any less bland. Rather its the DLC mission story and her reactions in it that make her less bland, however she keeps up that jadedness throughout the whole mission. I'm not really surprised as Bioware has a way with using the same character cliches in most of their games which makes all of their characters come across as bland and generic.
For instance, humans and quarians have hair while humans and asari have 5 digits, but they all have diferent skin collor.
You kind of put it out a bit wrong, rather it should be; "Humans and quarians are exactly alike except for being a slightly different colour, having two lines on their face, missing a few fingers and having weirdly bent legs. Asari however are a generic space alien all female race with tentacles, blue skin, scales and of course, the ability to mind rape you".
One is clearly the go to for alien babes
I mean no offense to tali-fans but she was significantly more attractive when no one knew what she looked like, i mean they had hundreds of pics of what a quarian could look like under the mask and instead they simply made them purple humans.
Suddenly that qt alien waifu is just a purple chick with limb deformities.
