And I mean, I can see why the species is considered the most boring by some for these reasons, but there's not much that can be done about it, and the reality is they've been there since the start and are a deeply integral component in Mass Effect lore. Despite the obvious pandering I do think BioWare did a pretty solid job throughout the trilogy embellishing them with mystery and integrating them into galactic politics and background lore in very sensible and for most part interesting ways.
I also think that despite the love-interest pandering they're pretty well designed within the confines of their aesthetic limitations. They're believable other-humans, if that makes sense, in the same way that Turian face plating is convincing so too do I feel the skin patterns, marking, and head tentacles flow organically into the Asari design.
