First of all, i think you are doing a decent job at trying to balance this game but scar should be fixed by now. I get it, you dont want to rush it but after patch C there is still no reason to use anything else than scar. Long range damage never was the problem with scar, it was its close range damage, i would even dare to say that scar have faster TTK than typhoon without losing range or control.
There is still almost 0 recoil when tapping, it still destroy everything at every range, to be honest i didnt felt any nerfs. I honestly cant understand why would anyone consider scar to be balanced when you compare it to: scarab, k volt, mike or ogr, i honestly cant grasp it.
Fy7 can only come close to scar because of rapid fire and even then its a lot weaker close range while not being really better at longer ranges.
Unless scar get huge close range damage nerf OR so much recoil that its unusable at long range it wont be balanced, mark my words.
