The 20-card limit really hurts one of the best parts of Diamond Dynasty: investing in the market.
Before this change, players could study real MLB performance, predict roster updates, and invest accordingly. It encouraged engagement with the live MLB season. Now that investing is capped at 20 copies per card, that strategy is basically gone.
Bronze and silver investments are no longer worth the effort, and the market feels much less dynamic because players can’t meaningfully invest in breakout players.
If the goal was to prevent market manipulation, there may be better ways to address that without removing a core strategy that many NMS players used to earn stubs.
Please take away this 20 card max rule or at least consider raising the cap (even something like 100–200 per card) so investing can remain a meaningful part of Diamond Dynasty.
