I think for the newer raids it makes sense. There are times when you'd like to gear an alt but the gear you have on said alt would be worse than playing your main, therefore greed helps. The likelihood of anyone rolling on the piece of gear you want is less since there's a weekly lockout. I don't think the ff14 team intends 24 mans to be the place to gear up your main toon, considering there are so many other avenues to get progression ilevel equipment. That being said, anyone hoping to get glamour in the old 24 mans is SOL these days.
