Sniping is pretty straight forward.

Being a great sniper requires:

1. Being able to aim.
2. Making the right decisions (when to go sniper, when to run, which target to go for, whether to body shot or headshot among others).
3. Your team effectively adjusting their play to utilise the snipers strengths and cover the classes weaknesses.

Being a “great” sniper requires all 3 points. Being a “good” sniper requires any combination of two points.

It’s pretty fucking simple really.

I’m not saying that the giude was bad or anything, but imo, Jones’ is better :D
