QoL Improvement - Challenge Event Reward Streaming

One of the QoL improvements I’m hoping for is adjusting the rewards for the challenge events. Some combination of the following would be very interesting for me:

*I’d like to see them stream the players, based on spending over the past XX months, where F2P, C2P, P4F, P2W are all competing against their own player type.
*I love to see them move to a similar rewards structure as tournaments where the streams of rewards are based on % playing, not numerical rank.
*I’d like to see an option to allow a player who successfully summons an event hero through the portal to re-roll which even hero they get if it’s one they already have on their roster. It should be an option, because sometimes you want more than one Black Panther.
