Different Approach to Mastery Enhancement
I would like to make a suggestion for a different approach to Player Mastery Enhancement. Instead of just earning additional Mastery points for finishing content, I would like to see the ability to permanently change a character's capabilities, possibly through the use of interchangeable ISO Gems that could be swapped in and out. One way to do this could be to change the Max level from 60 to 70. Once a player reaches level 70 they would unlock one slot for an interchangeable ISO Gem. These ISO Gems would be purchased through the store or earned for completing End Game content. These slots would be automatically opened in 6* champions once a certain rank is reached and available to be used by 5* champions once rank 5 is maxed. A few examples of an ISO Gem capability could be: Stun Immune, Unblockable Sp 1, Unblockable Sp 2, Unblockable Heavy Attack, Bleed Immune, Poison Immune, Defensive Ability Accuracy Reduction or Offensive Ability Accuracy Reduction. I think this sort of approach would bring an interesting dynamic to making older champions more fun and usable while not just earning additional Mastery Points, although I still would like to be able to add Mastery Points in the future.
