Unbalanced Stat Scaling & Position-Based Progression Flaw

I am writing to report a critical balancing issue regarding how player stats scale after training, which creates an unfair and illogical gameplay experience.

If you compare certain players (such as Alessandro Del Piero and Heung-Min Son) at their base levels, Del Piero starts with significantly superior stats. However, once both players reach maximum training (Level 30), Heung-Min Son receives a disproportionately massive stat boost that completely surpasses Del Piero, despite Del Piero having much higher initial base stats.

This inverted or inconsistent stat scaling means that high base-tier advantages are completely nullified by erratic training progression formulas. It creates confusion and unfairness for players investing in these cards.

I kindly request the development team to review and recalibrate the training stat growth formulas to ensure logical and fair progression for all players.

Thank you for your time and support.
