Deaths ---> frustration and angry shouting at screen " God d$%* fu**in game, arrrgr, give me my fu&%*ing xp back" ---> realization "hey, it's only a game man, and you are shouting at a computer screen, get a grip now, GET A GRIP I say!!!" ---> lastly, positive thinking "ah, that means more sp, don't it? Breathe in, breathe out, fff, fff, 1-2, 1-2, aaah, now isn't that better?"
Unfortunately the EULA you agree to every time you log in says that NC will not be responsible for any losses due to the servers being unavailable or having connectivity/performance issues.
Even if the server dies and everyone loses their weapons, you won't be getting them back.
