The ratio of material exchange to rep gains wasn't worth all the effort of putting in hours and hours of farming. That's the slowest way possible to raise your rep gains. 20 repfor every 50 materials you exchanged? You'll never get anywhere in your rep gains, you get 25 rep whether you win or lose in the Crucible. 31 if you have the Radiant Light buff, same goes for Tiger strikes. I'm only average in the Crucible, but I really don't care if I'm super TURRBLE or very good, win or lose, I'm getting my reputation and marks either way.
