So, I actually don't know why this wasn't a thing. I'm also just referring to the colour change. I can understand why they don't work on raid sparrows, because they have a very different plasma trail, but the SRL Sparrows use the same trails as normal ones. Considering the time, I doubt something this small would make it into RoI, but it is a small addition that would be nice to have. Who else likes the idea? Just another small pinch of customization using already existing assets to work on.
