English language is not my main, i'll do my best.
Because RNG in the loot system is too imperfect, here are a few suggestions :
1. Gear token system (only in Coil). You want to gear up, you must show up with the class you want to get gear on. Then, once you clear a floor, you get a special token. You clear 5 times (can be modified, debatable), you can buy the item from that floor. Can't get gear on your alt, since the token is printed by the job you used.
2. Gear token system, but possible to gear up all the alts on your main. I suggest increasing number of runs before you can buy an item.
3. Keep the same actual system, but take out greed option. Also, if all players pass on an item, the coffer closes, reset and open again, to give a new item. All players can try and need it. That way, we make sure 2 players get an item they need.
4. Same actual system, keep greed, but if all pass, new item.
5. Absolutely no change.
