Meaning that it follows the same system as hunts/FATEs: participation is required to receive rewards. Don't hit the minimum participation requirement, you get nothing, good day sir.

It's getting tiresome to see people in (outdated) 24-man content do nothing, release early to escape the fight, intentionally step outside or just generally AFK, secure in knowing that if they never roll for loot, they'll probably never get kicked for AFKing.

It's unsociable behaviour that shouldn't be as rewarding as it is currently.
