Recently looting seemed to change in 5 mans and only class specific loots drops for me (warrior) and there are items on the list to complete with stats like Agi and Int on items so they won't drop for me. Is there an option or filter I'm unaware of to take the off the list or is this an known issue being looked into?

Will there ever be an update to only apply that filter to 5 man's or areas where personal loot applies?

There's a new filter option for "Only Show Personal Loot". It's very VERY VEEERRY slow. But it will only list items that you can obtain while in a personal loot dungeon. Be mindful that not every mob in dungeons are forced personal loot, so you may miss out on possible drops by using this filter. (Also you should turn it off outside of instances since outdoor mobs aren't usually affected by Personal Loot requirements.)

There is currently no update planned to make that distinction. The setting is intended to be used at the user's discretion due to its bulky, expensive nature.

Probably worth mentioning that in BfA, Blizz is going to implement a old-is-new-again "legacy loot" mode for transmog hunting in old content: https://us.battle.net/forums/en/wow/topic/20761866700?page=1
