In a different server, 2 or 3 people and myself had a macro that maximumspammed the noisemaker...it kind of lagged the server a bit :|

-1
 
Interesting idea. The lag worries me, though.
Make it a donator benefit for trade/idle/Saxton?
 
I know it isn't just me that has HUGE problems with FPS drops. I'd actually have to find other servers to play on if tons of people started using the Christmas noisemakers. :(
 
Even though I'm not a donator, I say +1 to only it working for donators. It would be so annoying and I would lag extremely bad if everyone was just spamming this thing constantly. I can only get about 2 frames a second when a stupid medic uses the Meet the Medic Taunt, and during christmas I was only able to get at tops about 5 frames per second
