Jager, in my opinion the best MGer I've had the pleasure (and pain) of playing with, has mastered the one shot-no tracer-MG snipe, and when he is doing that it is really hard to find where he is at... he can shut down the battlefield until he is spotted.. so even though I've said I love the tracers (because I'm a rifleman and they make it oh so easy to find and kill the MGer) - I think the MG role would be 10 times as deadly if you couldnt see where he was shooting from. Maybe it could be made an option? I dont know how realistic that would be, but in thier absence the MG would truly gain the 'area denial' ability.
