Some things about the cards that should be changed or implemented;
like leveling the cards, since the implement of boss cards equip, is being ridicoluos hard to get new cards, having to gatter more 54 cards (LvL1) to upgrade just 1 to LvL10 and to get a specific card some times is more ridicolous since there’s no specific boss in dungeons, and in mercenary post everyone just want to go on Siulai, (“beccause is more quick and the exp gained on is the same as the others”) … so PLEASE RISE THE DROP RATE ON THEM …
And it could have some item to level them up like that “powder” we can use to LvL gems
Annother thing is a ‘Random card box’ as prize on events would be cool to get
Make them treadable trough players or/and via Market
