The no-sound jet packs are a no-brainer in that they need to start making sound. And the infiltrator's loud SSSSHHRRREKKKKKKKK! needs an adjustment in relation to jet-packs & footsteps. It's not about nerfing LA's or even realism. Some remote semblance of realism does need to be approached. The current jetpack silence to tank drivers and other vehicle occupants is fine. It's shotguns that need to be tweaked, not LA's. LA's aren't the problem other then that one thing: silent jet-packs.
