Would you be interested in a subscription-based service?
If Kabam were to offer a $9.99 a month subscription that would allow you to do things like pick your own avatar and also give you bonus items when opening crystals that you wouldn't normally receive (like an extra 750 T4 Basics on an Uncollected Daily Crystal, or a bonus 55 4* shards on a dupe, etc), would you do it? I only ask because I've seen this done well in a few other games, and it's been pretty helpful.
