Blast sheild needs to be buffed because for the most part its worthless compared to the other perks in the same tier. i should never die to explosives unless i have already been injured by some other means. i was killed by a gl with full health and thats just straight up bs. of course, kill streaks are exempt ie pred missle ims ect. the pro version also needs a buff the maximum amount of time stunned should be 1.5 to 2 sec per nade. doing this might also encourage people to use other perks rather than quickdraw or assassin.
