BRD groups, 60s and <60s?

Is it possible to group BRD with people at 60s and people below 60? If not, is there a chance to fix this mr blizzard.

It’s a dungeon. Of course it’s possible. People who only want 60s are people who run it for specific drops. People below 60 have quests and more.

i’ve done BRD with 60 in group while being 51. hunter accidentally… accidentally looted my healing mace in the Vault.
