Instead of packs with a bunch of items I don't need, How about creating a pack with fragments of Leggos I do need?

With all the Fusions and other ways to spend energy how about giving me the ability to buy Fragments of leggos?

Food for thought. 

To make it easier, how about universal fragments to complete fusion builds, I am sure there are plenty of us missing 5, 10, 15 or 20 fragments to fuse heroes.
