What would be the point of putting it into DF then? Skipping turns? No one would do that if loot is still locked out. And how long? Will it still be locked out with Echo? So you queue in and then discover some guy already looted so you get one chest? And the way the system informs you about previous clear flags would have to be redone anew which is a silly effort.
They don't have to explicitly mention it because Coil doesn't have a loot lockout to begin with - only entry lockout. I've seen people use helping system as an argument that it does but that's not what it is, you can't freely enter turns after you've cleared, you can only tag along with a guy that's on previous fights. Coil loot rules are strictly intertwined with it being off the normal queuing system.
hmm good point, totally forgot about that
