@Jythri can we get daily&weekly challenges? Rewards could be loot packs that vary on par with difficulty setting, some could be for solo, duo and full groups(including any group over two) that would scale accordingly.
These can be separate from the lore and character unlocks etc…possibly high level challenges and sub missions within the normal campaign to cater to those that have worked themselves out of PVE things to do?
Or character skins could be unlocks as well potentially.
Time trial mode, or an extreme difficulty where there is more shielded enemies or their defense are higher.
