They ban DSR+r because they can't ban players with good aim (they would if they could).
They ban Scar+laser because they can't ban players with good aim (they would if they could)
At first, yes the headshots with DSG'r looks **** sixy. But i can understand admins who ban this weapon from there servers.
Yesterday i was in a server with nearly only DSG'r guys and it's just annoying when you get hitted once you know you will die. And i was Scarab + Laser and on Longe distances is DSG'r overpowered in my opinion. And as Stormaj said, that you need very good aim with DSG'r, well, i would say no to it. You just need Low DPI and Low Resolution + some days of training.
I have a to high DPI on my mouse to play very good with DSG'r but still i can give some sixy Headshots.
Next, Yes Scar + Laser is bugged but you need stilll aim to kill someone, so ppl don't like Scar + Laser because they are die to fast. Same for us with DSG'r, 2 hits and you are dead.
P.s. I have nothing against Dsg + Reflex.
