I disagree with upping FPS because players are too deaf to notice the loud thwack that even I can hear across the field. The game is of honesty, if a player is dishonest, they shouldn't be playing.
Feel, see, hear, taste the bb.
I also disagree with overfiring personally, and I won't do it myself; since many times after I've called hit, many people continue to lace bb's into my throat and other tender areas since they're either blind or deaf apparently to see me yelling with my hands flailing. I've only really had issues with this lately, though.
Being a good player takes time and getting used to the hobby. We were all there, so I will give it a pass most of the time. However some people are just assholes.
