What I find surprising is the amount of bcx in PACKS vs what we give up in rewards.

You used the example of 47M in Chaos Legion.
Current Reward Cards are 32M --> going to 64M in 5 months.

Packs are revenue-earning, go to the bottom line of your business.
Rewards cards are not.

I think you need to address several things as a business:

• CORE set cards or mini-set should be highly desirable. This is why people need cards
• Rewards cards should always be "weaker" than or less desirable than a CORE set card. Otherwise, once I have enough "rewards" cards, I never need FULL CORE SET cards. Reward cards should be more situational ones or used to counter other cards. But CORE cards are better and more well-rounded.
• Inflation of the reward cards are impact all card values. This can be fixed if reward cards are not as good as CORE set cards or any cards that we buy.
• Promo Cards should be special. But if someone can use 6 reward cards to beat others' cards, this is what causes less value of CORE cards.
• Summoners should not be part of reward cards in the future. Summoners are the one card you must play in each deck. They should only be in CORE Set or Mini-set, which is purchased, not earned.

As a bronze-level player, I have been able to "reap" more benefits from this SB-reward card release because of the FREE SUMMONERS. Summoners should never be part of the reward card set. Most of my CL summoners are at Bronze LEVEL. I have silver league SB summoners already.

I will vote with my 1800 SPS, but I hope people can see that wisdom is not often related to how many SPS one has.
