I guess another thing that kind of grates on me is the fact that Protheans as I developed them in my headcanon are about the polar opposites of how they're portrayed canonically. Canon-Protheans are all "RAWR FIERCE ARROGANT PREDATORS WHO KILL OR ASSIMILATE EVERYTHING" whereas mine are inquisitive, hyper-intellectual, study-obsessed "somewhere-there's-an-ivory-tower-missing-its-wizard" types.
So, who would win in a battle if the two races fought?
....
Canon Protheans. Hands down. Mine aren't good at fighting.

"Victory be mine!"


"Congratulations, you've just inflicted a SECOND genocide on the only race as advanced as you."


"......."


"......."


"I'm gonna go t'row meself out de airlock, mon."


"That's right."
