Cloak mode, killcam

Hi there!
I notice that cloak mode in campaign is a little bit silly, when you activate it enemies just standing there, you can shoot them in the face and they do nothing! So I think, they at least should try to hide a little…
My other problem is the lack of this visible,red damage taken "thing"around the screen, when watching a killcam after death. I know there is always a percentage shown, but when I watch replay I wanna see how hard I hit 'em before I die. :v:
