If you snipe, you know you miss shots sometimes. It doesn't matter if you are a god at sniping, you are going to miss a shot. Getting a 100% chance on a mulligan in PvP is rewarding as hell when you get limited ammo from the start.

Don't act confused and try to flex like "I never miss shots." Your opponents get better and better as you go, they are perfectly capable of flinching you or ducking and rolling as soon as they spot that red light in the distance.
