It is recommended that EA release the drop rates of cards in the pool.

The FUT Birthday event concept is great, and player customization is highly playable. Three daily highest-89 guaranteed SBCs, one FUT Birthday Team 1 SBC, plus various packs make it seem like there are plenty of ways to obtain Birthday cards. Yet despite all these avenues, I cannot pull any cards worth over 50k coins. Out of 29 FUT Birthday cards below 89 OVR, only 4 are over 50k, giving a theoretical pull rate of 13.79%. Only 8 are over 20k, a theoretical probability of 27.58%.

Since the event started, I have opened 15 max-89 event packs and 5 Team 1 packs, yet not a single card over 20k. Your drop rate settings are definitely broken. EA, you should release the pull probabilities for every card in the pool, or disclose the setting logic behind the card probabilities. This opaque packing is nothing but a rigged game controlled by the house. Additionally, publishing drop rates would also silence claims that only paying players can get good cards.

The current drop rates are far too low; they have completely ruined the experience of this event. The team responsible for these settings means that even with a great event concept, you only receive negative feedback and face player backlash.
