It keeps me up at night worrying that people will discover its potential, and hoards will learn how to use it, which naturally means people will learn how to play AGAINST it, which means I would no longer be able to get easy kills with it.
I found out how good it is sniping. ;) Where's my cookie?
You do relize that this idea is a rebalance? Not a buff, if it was a buff, would osk with or without Heavy Armor or both Heavy Armor and Light Armor?
Right now, PR has a tiny OHK range. Just the head. What you are suggesting would widen it's OHK range to also include the entire torso. How is that not a buff? All you're doing is increasing the damage the PR does to other parts of the body, making it stronger.
This would just make one of the strongest weapons in the game stronger. Which is not needed. If anything, it should be made weaker, as this is supposed to be a high health FPS. Either that, or make the weapon harder to obtain (weapon pickups instead of loadouts).
