Name : The hard-hitter

Oh.. i forgot.
Advantages :
1. More damage, tends to survive and snipe off targets
2. Annihilates heavies
3. Frustrating if he has good aim and/ or a good spot
Disadvantages:
1. Machina. You get close to him and he is screwed.
2. Needs a good shot to get the CC kill.
3. Tribals, -50% dmg. Self-explainatory.

Thats my tip.

I have a good loadout set for a sniper who has his aim and likes to hang far away. Machina - CC - Tribal's. Machina? BOOM, 518 damage. Cleaners? Clean up if got 2-3 shots, and want critz. Tribals? If they survive on low health and you die, they will come with you.
