Spook interesting point.
There is a difference between nice shot and "OMFG WOW, HOW DID YOU DO THAT IMPRESSIVE SHOT!"
One is a common courtesy in a FPS. (This common behavior stimulates growth and report)
The other is an acknowledgement of a spectacular move.
So say say nice shot, when you get shot. It wont hurt you and if you choose not to ok but if you do get shot dont act like an ass.
excretory openings FTW and DP growth?
I think not.
