I mean my argument is, "she's written as a teenager for her fantasy space race." Which is like asking what's my rebuttal for the Ring of Power existing in Tolkien because magic isn't real.
I'm just pointing out what the games were presenting.
She's an Asari child prodigy which is a major killer for romance from my part, in-universe fifty or not.
I mean falling in love in a dangerous situation and showing interest in someone's issues to help them out don't strike me as particularly bizarre elements.
Mind you, I think Leliana and Morrigan are about the only romances in games I think that actually worked.
My wife says the same for Alistair.
Alistair usually doesn't like me by the end of the game, regardless of what I start out as, penis or vagina. Generally the only characters that like me regardless by the end of the game are Dog and Oghren.
Zevran, I do keep around most of the time, especially if I'm not a rogue. Though he does get uppity about certain things.
Wynne goes apeshit at the Circle Tower and I inevitably kill her.
Sten is schizo about decisions most of the time, so I'm never clear about what sets him off.
Shale... I usually never bother to pick up.
Oghren really only cares about what you do in Orzammar.
Morrigan, I generally keep as an active party member if I'm not a combat mage, but shoot her advances down each time they arise.
Leliana is never brought on at all.
Dog is a dog, so he does whatever regardless.
Alistair, depending on how I play, might be my best friend at the end of the game or more often than not booted from group or executed.
Also the companion bickering is another thing that bothers me and is a big reason why I may avoid certain companions.
