Weapon balancing is actually comparatively easy compared to the atheon bugs. Imagine lines of code, all with different values. All you have to do is tweak the values (deleting current value, inputting new value) test it and boom, you're done. The values are everything and anything. Reload times, Damage, rate of fire, field of view, character movement speed. All assigned a numerical value. Increase numerical values for a buff (generally) decrease them for a Nerf (generally.) I just honestly think they don't care. Or the atheon bugs are overwhelmingly complicated (pretty likely.)
