This weakaura will automatically roll on items the way you've set it up in Custom Options for each difficulty and rarity of item. Each difficulty can be enabled or disabled. The weakaura is currently loaded in Shadowlands raids. Dragonflight raids can be adde with their respective ID in the "Load" tab. You can also seperate each dungeon with their own individual roll setups, simply by duplicating the aura and editing the Load IDs.
Why use the aura?
With the removal of personal loot and the lack of master loot, our guild have members pass on all drops and our raidleader need/greed on everything. With this weakaura, you can set that up quite simple.
The raidleader will set his WA to auto Need on epic items, and enable fallthrough (an option that will automatically pick greed if you are unable to need on an item).
Raiders will set theirs to automatically pass.
Everyone will enable "Guild Group Only" and define how many percentage of the raid needs to be guild members for the weakaura to take effect (Default 60% since that's what blizzard defines as a guild group).
If any requirement aren't met, no loot roll is selected. E.g. if you enable "Guild Group Only" and set it to 80%, but only 60% of the raid is actually in your guild, the auto roll rules will be ignored and you'll have to manually roll for items.
