I think the key to getting one is being a good Ns player, not most kills, but well behaved, and not whiny...
I belive i told them i wanted one ONCE in the very beginning, never said another word, and just bit as many rines as i could...ehhehe...
but seriously, if your on and you have to ask why you dont have a reserved slot, thats prolly why, I know I wouldnt like beign nagged at to give someone a gift...
but now that i have one... *strokes reserved spot* my precioussssssssssssss
