What's something you feel the fandom tends to overlook or forget?

For me, one of the big things is the fact that almost no one in the Galaxy--of any species--knows about the Genophage modification project.

We see the Genophage first through Wrex and then through Mordin's eyes. Most people don't.

As far as most of the Galaxy is concerned, it was something deployed by the Turians (maybe the Salarian role in its initial development is known) over a thousand years ago.

The fandom (and maybe Andromeda to some extent) seems to act as if most of the Galaxy associates current Salarians (and disassociates Turians) with it to a degree that only makes sense if you know about the modification.
