I think it should be nerfed, it's like the CS awp which we all know is so easy and cringe.
Just random idea, maybe cool idea is u have to press extra button to activate slow once u kill someone. So u shot someone, they died, then press button to activate slow. This is like address 2 issue, first u can put amall delay so easier to trade, ( u are not instant slow , chamber have to activate slow ) also its annoying when u. Chamber and get self slow, so if u can choose to deploy slowing field or no... its better, so its nerf and better i guess ?
