2.Balance Skill
Some characters have clearly weaker skills, please buff their exclusive abilities.
Also, will there be new skills in the stamp card that are getting stronger every season? That’s concerning. It risks turning the game into a "spend rsr or real money each season to fill that season's stamp card or fall behind" situation. Instead, consider putting stamp card skills into the Skill Shop so both F2P and players after the global launch will have a chance to get them.
Another worrying point is the mention of skin-exclusive skills in the Q&A. Please don’t go down that road. Let's be honest—the dev team can't ensure proper skill balance. If every skin has unique, varying power-level skills, the game will fully enter a pay-to-win era... and likely end up like every other failed p2w game.
