Snipers should:
Have longer firing range than sight range. 360 sight would be 32.
Ability to focus sight (like looking through the scope). Similar to SU85 focused fire. Narrow cone, but long sight. RangeOfFire = SightRange = 50
That would also mean, that in that mode of fire, it would behave like a weapon team. Would be an extremely short setup time (to breath in, look through the scope and start firing), but would be a setup time.
Increase the Target size to 2 or 1.75.
Remove the slowdown after firing. Maybe some other offensive changes like RoF would be needed, but it would fix snipers retreating and not dying. Something I've seen aplenty.
High risk high reward. On one hand, if it's properly screened/supported by infantry, then you have no worries, but if you play a RolePlayingGame with your sniper, good luck surviving anything that comes close to you
