The SCAR is the most used gun no doubt and the main reason is not because its the first gun you start you start off with, its because its a niche in every role or some may say Overpowered.
I think that the SCAR should be a crutch that doesnt have a niche but works in all ranges you use to hobble up the ladder and unlock new better weapons that work better in certain niches but instead your starting off with the best of the best. At the moment the Scar is beating other weapons in their own niches. This is wrong.
I think a simple damage Decrease of 50% maybe abit more would fix this, everything else is fine, ( although maybe it could the same recoil in Campaign? where the longer you spray the more out of control it goes. )
At the moment this is where the Damage stands.
2 shot kill on a cloaked opponent.
4 shot kill on a neutral opponent.
6 shot kill on an armoured opponent.
note that all of these results were performed on people with full health and energy.
This is what I propose.
3 shot kill on a cloaked opponent.
6 shot kill on a neutral opponent
10 shot kill on an armoured opponent.
This would put it on par with the Scarab in kill times. As it stands, toe to toe two oppoenents firing at the same time at eachother, all bullets hitting, the SCAR will win everytime despite the Scarab being a late unlock.
Also I beleive that the Scar has better range than the Scarab, and at the moment it seems that the only viable reason you would choose the Scarab over the SCAR is for the Silencer for stealthy kills.
