I think the general community consensus that Dead Silence should be a perk is a fucking terrible idea, for the record. We don't need it being a ridiculous clutch that results in players being unable to respond to players sprinting at light speed and jumping around corners to hose anyone who's actually holding a choke point. Having it being an ability to activate on demand is a great solution, and should remain that way.
Map design with actual flow (rather than dozens of random rooms to nowhere that don't exist for any purpose other than camping), claymores having a significantly longer fuse, bouncing betties being completely avoidable by crouching (not just prone), and so on are solutions the game needs. Making Dead Silence a perk is a band-aid, and would only make campers more obnoxious, since they would be able to not only hide with ease, but reposition with ease as well.
