The simple reasoning behind this is to make strike and raid bosses a "challenge" and not have the boss fights basically become a fireteam flinch locking them until they're defeated. To me and actual players that enjoy this game i agreee with it 100% because it makes the fights last longer and more interesting. You guys cry and whine about it as if its useless, when you can basically move a few feet from your position in the game to pick up special ammo from a dead enemy. It's honestly pretty sad how you guys can't see the reasoning behind it and need other people to tell you.
