Epic Rift Awakening Gem
I very much like the Rift system -- its enough incentive to play daily while also not being too overwhelming.
The balance of task and reward is solid.  
However a recommendation to the incorporation of the Path Selector, we all know people are going to save and purchase it to select the Awakening Gem.
With that being the most likely reason someone would purchase it.  I think it would be a better system to have the awakening gem cycle as opposed to being RNG based on which one is shown. 
I've gotten both Mutant and Skill twice out of 4 runs.  Im waiting out to get Tech so I can awaken my r5 Stark Spiderman
I dont want this to appear as a complaint, but instead a way to incorporate more of a cycle and not strictly randomness.
It would allow for me to know "in X days ill get it" and not be getting the same one two runs in a row.
