Decrease the shotgun "accuracy"

Example for 12 pellets: https://i.imgur.com/6tM2RiS.png
Each pellet could "spawn" somewhere in the area of the red rings. An easy way to program this would be to map out the initial static spread, then simply change the position of each pellet by minimal values (whether positive or negative, on both the X and Y axis).
I don't know how spread works on GunZ though.

Easy. I have done 2 static patterns before.
1 which is exactly like yours in the image, and one which is like this https://puu.sh/xrmNW/b13b83cf58.jpg (the better thing here is that 1 pellet always hits in the center, where with the 4x4 all pellets could miss the target if too far away).
Both are even still in the FG code (but disabled).
Adding a small random offset would be easy to do and possibly be a good solution. I can test it out and play with the values.
