There have been some necessary adjustments to the EPGP system we use to determine loot during Progression Raids, so I wanted to make sure to inform you of the changes, why they were necessary, and how they affect you. (See bottom for TL;DR)
Why do we need a change?
The equation that the addon uses to determine Gear Point (GP) values scales exponentially with item level. Consequently, we needed to drastically increase our Effort Point (EP) values from last expansion to keep up with the exponential growth of GP from Legion raid loot.
However, after we assigned the values for the new raid tier, the EPGP creators adjusted their equation to make the numbers scale better, causing a massive disparity between our new EP values and the GP from items in Legion raids. Consequently, players who had completed the Pre-Expansion EP items were not properly falling to the bottom of the Priority Rating (PR) list for subsequent loot.
This scaling was completely unacceptable and needed to be changed immediately!
How did we fix it?
We corrected this scaling problem by adjusting the EP values players receive from all sources to correctly parallel the average GP gains from Legion raid loot. From now on, instead of receiving EP in the tens-of-thousands for your efforts, you will be awarded EP in the hundreds.
Moreover, all EP earned from Pre-Raid options and from the first week of raiding has been adjusted using a conversion factor of one-thirtieth (1:30). This conversion will now properly rank players with an equal weighting on effort and gear (instead of unfairly favoring effort). Players who have not received loot will now appear higher on the PR list.
For example, the broken formula incorrectly placed me (Barotar/Benedictas) at 5th from the top above players who had not recieved any loot yet (even after receiving a heroic/warforged trinket). The new system now correctly places me second to last.
Here are the specific changes:
What is the impact of this change?
The order of the PR list has changed as a result of this adjustment. Players, like me, who received loot during the first week of Legion will notice that their names are properly displaying at the bottom of the PR list while players who did not receive loot in the first week of raiding should now appear higher on the list.
We fixed a scaling problem with EPGP that (if left unchecked) would unfairly bias players who earn more effort points. The system has been adjusted, and players who received loot in the first week of Legion are now correctly appearing below players who are still waiting on loot.
