As the title says. Equilibrium is an "utility" Mod to my eyes, which should make it eligible to be Exilus. I would use it more often if it were. Tell me if I'm missing something, but I don't think so.
When exilus was announced as utility slots I proposed natural talent be an exilis mod. That didn't happen but we have speed drift offering a similar less portent bonus. All logic goes out the door then, an issue further exasperated by having power, endurance and cunning drift. De will do what they'll do and consistency is out the door.
