Alternatively, we could also make the recipes and materials dropped from the loot boxes non exclusive to the world boss. Just distribute them to several normal monsters and we can leave the 20-30 players their bragging rights. We could also distribute them as rewards for new quests or set up a point-exchange system for these recipes and materials, as long as we un-relate them to the world bosses.
Setting the recipes and materials to non-tradeable is another option. We’ll see how commited these 20-30 players are to killing the game if they choose to continue killing world bosses despite not being able to market any of the loot.
By the way, has anyone posted a list of these 20-30 top players? I’m sure there are others curious as to who they are. The top 1% anyone?
