I don't think there's any misunderstanding. The de facto point of view on these forums is more or less what you just stated.
There's a lot of posts that are saying they should not add the /roll because of ninja looters. I was trying to explain that the /roll that we are talking about is not the need/greed. That just because someone types /roll and gets a higher number doesn't mean that the 'ninja' roller is going to get the gear.
