It's not your spelling. forget forget forget. Hey look no censors. You can swear. Doing it excessively and blaming your "tourettes" will get you banned probably though.
The thing is that every single idiot in blockland who hosts will have this weapon and host some stupid deathmatch with this. Not only will it cause extreme lag from everyone firing it at once, it'll degrade the deathmatch to the point that everyone who wants to actually play a deathmatch will get pissed and leave.
Not to mention every host will see at least like 10 people who join their server go "do u hav nook?" and then go "omfg yur a noob host" if they say no, and leave.
tl;dr: We can't have it because it lags, ruins the game and is stupid. Go play a game that can handle a nuke like CoD4 or Crysis.
