yeah, people forget luck is a thing....
take it from someone that just had a lot of luck on kami pulls... after a long as hell dry spell....
besides, i'm sure there's a way to look up their drop history or something cause you do have to match what the server info says. stuff like that would mean hacking the server directly to look legit for item drops, jewels, star coins, and such. cause the server digs the info on what drops and pulls you got, then feeds that info to you.
changing it means either direct server hax or "hey look at the obvious difference in info due to hacking!"
