I was wondering if there was any plan to update the percent drop calculation for drop tables. Right now, the % drop is just a straight forward calculation of x times dropped over y items dropped.
This doesn't take into account quest items. Some quests guarantee that 100% of the time a mob will drop the quest item if the player has the quest. Other quests do not guarantee the drop. Plus special times of the year (Halloween, Christmas, etc.) will give x% chance for a festive item to drop while outside the special time there will be a 0% chance for the festive item to drop.
I'm not claiming to have any answers, but the current system is lacking certain key elements.
I just wanted to bring this issue to the attention of the devs.
Thanks.
