I was doing classic dungeons with my warlock while max level with party sync enabled - it scaled me down to level 60. When I completed the dungeon I received a "Salvaged Cache of Goods" (https://www.wowhead.com/item=171305/salvaged-cache-of-goods). It contained "Felsoul Shoulderpads" (https://www.wowhead.com/item=173655/felsoul-shoulderpads). After two more dungeons I also got "Felsoul Wristwraps" (https://www.wowhead.com/item=173657/felsoul-wristwraps) and "Staff of Swelling Agony" (https://www.wowhead.com/item=173572/staff-of-swelling-agony). It appears that doing dungeons with party sync on rewards a random class specific item. These should be added to the addon.

See the chat.

i added them on git like an hour ago! they'll be in the next update.

Thanks! :)
