Hello, i couldnt find this setting, but right now I see loot in main/mini ATT window that cannot drop for my specialization.
1 example is Yarxhov the Pillager in Korthia as a Death Knight. SilverDragon (with class-specific filter, does not show loot there). ATT shows a 2h agi weapon "Fallen Vault Guardian's Spire" as possible loot. I killed that elite 30+ time without this dropping, so this could be false.

Please guide me in case im missing something. Thank you for amazing addon.

Note that my intended addon behavior is to only show all possible loot that I can get relevant to my class (incl. all roles, so i can decide if i need to choose loot spec)

Same applies to rift boss in Korthia "Observer Yorik" dropping "Rift Splitter" which cannot drop for DK's. Checked on wowhead.

If we ever address some sort of Personal Loot filter in the future (which will be inaccurate since Blizzard's data for specs on Items is inaccurate and that's how we get our data) then this would be covered in that update. But for now, adding that additional filtering is not going to be a priority.
