Even with reduced range/damage, players still do a lot more damage by flanking and killing multiple enemies without being detected almost indefinitely. The reduced range/damage negative is not a factor when players are able to get close enough, or if their targets are just at the edge of the already reduced range. In MW3, Assassin/Suppressor builds were extremely powerful, especially when multiple players use them, or when they are used in Hardcore (imagine if the entire enemy team ran that, add Dead Silence, in Hardcore; no amount of UAVs can do sh*). Even if Recon exists for this reason, only like 1% of the COD population ever uses them.

If they don't want to add a perk, then they should change Amplify to be able to hear silencers and still see them on the mini-map.
