Have Vulcan tracers been tried on T7-Mini Chainguns before? Maybe tuned/scaled down a bit. It would be mostly to attain a visual warning similar to the Lasher, which has a similar supression role in some situations. Cons would be visual noise and visual unconsistency as it's not an AV weapon.
Wouldn't mind it too much. Not that it was too hard before, quite easy to follow the noise and look where people get minced by it to figure out its location.
