This may be a coincidence, but this worked for me pretty well this past mode (just got the 16th crystal this morning). If a level was being stingy, aka played it five times and no drops, I would play it through once or twice and NOT finish the boss with a power attack. I usually got fragments from those times. Then I would switch back to finishing the boss with a power attack once I had two fragments and it would drop them pretty quickly.

Additionally as a point of strategy, I would always work on two levels at the same time until I get to Kingdom of Darkness. So for example, if I already had 6 crystals, my main level would be Writing Cascades, which I would do two battles on, but I would also do a battle at Guardians crossing. That way if one level is being stingy I can still make progress on the other.

Finally, I only use my friends for heroic mode now. Even if you just get the regular version it is still way better than anything you get from the epic boss.
