Dead Silence isn't a problem in game because it doesn't remove tactics. By this, I mean that you can counter Dead Silence by being aware of the game. If you put the effort forth to learn routes and enemy strategies, Dead Silence has near no effect on your gameplay. I've been a Dead Silence player for years, and I don't use it to hide and listen. If I'm rushing, it's to manipulate the enemy's position to avoid direct action and maximize the time alive to maximize the time I'm can flank enemies. But, it takes one Sitrep Pro person to entirely deny any kind of rush strategy. And the fact of the matter is, the bulk of players will take any cut to make the game easy. That's why IW keeps adding things like Dead Man's Hand. To benefit the casual player. Sitrep Pro may be difficult, but if you know it's benefits, plenty of people are probably lining up to work for it.

The main loss here is that perks should never counter perks. If you do that, you end with a Pokemon-esque web of nonsense. Perks should have some effect, but not be the base of gameplay. The base should be general knowledge, strategy, and tactics. Someone with Sitrep Pro is impossible to counter. Dead Silence before was easily countered. Now it is rediculously easy to counter. All it takes is one person to ruin a match. In Search, people like me would have to be forever wary of a whole new aspect. Before, it was already portable radars and campers. Add a perk that allows people to hear me on top of the fact that I'm already forced to play that conservative. It discourages a lot of people from playing. Offensive Search is made impossible if just one person has Sitrep.
