Sniper only takes 50? You should give the head, torso, and anything else specific damage regions... So people just dont shoot whatever on you they can.
Head - 1 shot kill
Torso - 50 dmg
Anything else (hands, feet, legs) - 25-40 dmg
And make sure it isn't that lame.. Sniper's are always really easy to get very pro with, and just kill any/everybody.
