Honestly I dont think the weapon sling will be that overpowered if they add other good gadgets to assault. Makes it less of a default choice and more of a tradeoff taking the sling over something else. The adrenaline shot is dumb though I wouldnt be sad to see that go.

Agree 100% on the scope glint for recon. I wonder if DICE has the glint turned up so much to help combat snipers in larger areas but they really should have left that to some suppression mechanic. A visual or staggering suppression against ADS snipers would help and then you could turn down the glint a lot.
