In the 0.8 update, we made some controversial changes to the Hero Crate. We listened to your feedback about how the community felt we had devalued the Hero Crate. After an internal discussion, we reviewed the number of Fragments needed to achieve each Hero Star Rating. We felt we could bring more value to the Hero Crate if we modified the number of Fragments that are required to evolve the Star Rating. We felt the number of Fragments the Hero Crate gave out was too few and the number of Fragments needed from 9 to 10 Star Heroes was too great so we redistributed the required fragments to have a more smooth growth rate.
The most notable change here is that a 3 Star Hero duplicate will reward 60 Fragments, where it previously generated 35 Fragments.
The Fragments per Star have also been updated with this change. you can find a chart detailing the changes below.
