The Elite scheme hasn't changed except they took out crates to erase the biggest luck factor on FB, like Mablak said. Not sure about Cluster power.. That is from 2002 on, when I started playing Elite. Don't know about before that..
Does anyone still have that EliteLeagueAM scheme? Wasn't it built in to the game at some point (or patch)? Wasn't it the original Elite scheme?
