If you're upset about this you're missing tౠhe point.

Tr♌ading being limited to diamond rarities lets the F2P players catch up on cards for deck building. That's all it needs to do. Opening trades to all rar✱ities will get everyone excited, for the few weeks it takes for everyone to complete their sets, and then the game will die off from lack of interaction.

And from a business perspective, the whales and dolphins will keep spending their 𓄧money to get gold and pull their packs. If all rꦡarities are open, it will disincentivize spending money to pull packs. Or worse, it will create a secondary market where people will trade their cards for real money.

I don't see any way for trading to be fully unrestricted without hurting the game's longevity. If you have a suggestion, write about that instead ꧃of just lodging a complaint with no solution.
