Its no good a PC player saying a gun is highly inaccurate if on the console version they are not. A tweak then applied to both groups throws the balance out for the console. This is why separate platform feedback is required.
Watching that video I can clearly see that the player in question is able to pull off shots in game that I know for a fact you cannot pull off without ADS on PC. On PC I can shoot someone 4 times at point blank range and miss, on the video this guy is firing 4 shots at mid to long range, rapidly and hitting almost every time without ADS. There is a clear difference, however my feedback to say the gun is inaccurate and needs to be buffed in order to make it usable will cause in-balance on the console because it does not. In fact if my feedback based on PC experience was then used to publish a tweak to both platforms I would be indirectly causing an overpowering of the weapon on consoles.
This is exactly the reason a separate set of feedback is required. This is not an exercise into segregating the Brink community, or saying PC is better then Console its just to make sure that feedback is correct for the tweaks that will be made to each platform.
