There were plenty of groups who would hit that in 10 minutes and get fairly annoyed that they were forced to spend 10 more minutes in a quest and get no added benefit. This change allows you to collect more than you previously could.
During the preview day, I ran it twice (solo), collected less coins than I would normally have had to and walked away with 196 each run. I didn't collect 296 in total value of crystals. I was fairly rusty and not running an ideal solo character in there, so I also wasn't killing any extra mobs.
This is just one guys perspective, but so far it is better.
