I made an account just to post this. I looked over the first page and saw a topic already about riot shields in search so I assume its been brought up before. These two things have absolutely ruined search and destroy. Amplify has literally reduced me to crouching around the ******* map as soon as I get over to their side of the map because people just sit there and wait for your footsteps. I don't even care about campers, I can deal with them almost every time; I'm sure you and your buddies have 10 I.E.Ds set up in the room anyways, but when they're camping AND know which direction I'm coming from? Its over. I don't care for any other game-type, search is where the best players play and requires some actual team-work and skill.
As for Riot Shields you can't even run away from them because of the strongarm perk. In search each round they respawn with 2 more c4s and probably 2 rockets. In a round of search thats a automatic 2 kills at least which is 33% of your team gone right there. Let me at least shoot through the damn shield with armour penetration or when they're throwing the damn C4.
For the inevitable people who are gonna say I cant adapt I did. Now I sit there halfway up my spawn with an assault rifle waiting for 2 minutes before someone has the balls to leave their spawn and finally plant, and the sad thing is- it works.
