I recommended something on the Team Fortress 2 forums to this effect:
- Lever-Action Rifle without the Zoom Ability.
- Crosshair grows and weapon becomes highly inaccurate while moving.
- Standing still quickly shrinks crosshair and makes the weapon 100% accurate.
- Deals huge damage to the chest, weak damage to legs/arms/etc.
- Deals double damage to the head when 100% accurate.
- Firing causes the weapon to become slightly inaccurate/crosshair grows.
- Therefore, standing still reduces refire rate.
Allows the Sniper to snipe slow moving classes in the head and drop them in 2 or 3 hits. Also is only practical at medium-close ranges where the Sniper can be interacted with. Requires a huge feat of skill to pull off at long range, but the ability is still there. No damage falloff.
