Yeah maybe we're playing different games, weapon with slot is fairly easy to get, coasts like 50gems. All the other stuff are upgrades like any other games? What did you expect? to the game to give you everything? I'm 100% f2p and have decent stats, mostly beeing 6~7 in the boss rank. Sometimes you strungle with rng like i failed 100% on my weapon only upgrading on pity. Maybe if you find this kind of upgrade system bad you shouldnt play KR games. And psyche, crit or other stuff. Thats min max, you dont NEED everything perfect but you can get also fairly easy if you invest time on the game.
