this may be a very stupid question but in what case do you buy a d2? and in what case do you buy a d4? I have been trying to research this but nothing, can someone just explain it to me like a 10 year old? //content.invisioncic.com/y282845/emoticons/crap.gif.7f4dd41e3e9b23fbd170a1ee6f65cecc.gif Mostly what i got from it is that you buy d4's when you are gonna run more than one and a d2 you run alone, maybe? or am i way off?
