@SpyrosFPS The R99 gives you a lesser of a chance of hitting your enemy. Spitfire gives you 55 chances with a purp mag. Not to mention it is much easier to controller and you can be a lot more accurate with it. As stated before, I have taken out entire squads with the Spitfire, I cannot do that with an R99 because of reload.
In regards to blinding enemies... You are 100% correct. I have no idea if this is intentional (if so remove it) or if this was an accident. But, I would agree that the L-Star being moved to an SMG class would be a better place for it (To me that would be a buff). I haven't seen it used like an LMG, it is always used up close and not mid ranged.
