Considering the 1 or 0 chest thing was only implemented in Alexander, nope. There was a similar thing at one point in coil but SE dealt with it, faster than this problem, so it is a wonder what the hold-up is.
This should have its own thread so it can gain traction.
My static only meets 2 a week. The whole loot system makes it impossible to try and practice between raid days for fear that if I happen to clear with a PF/RF, or attempt anything above V1S, I'm going to screw 7 others out of loot.
IMHO, it would make savage raiding a lot more accessible if folks could practice without fear of loot lockout.
Not everybody play this game just because of loot. They play this because of fun and have something to do. Some players just want improve their rotation in current fights or try how they perform with different role/jobs. Many player that like to raid more often have alts so they can do raid multiple time in a week especially streamers do that often.
I tested this, you are correct. They see the chest open up, but cannot lot.
Thus I assume they are there to 1) well troll.
Or
2) Genuinely To help out. Considering I joined to help clear - said 1 chest is fine. so yeah.
But mostly
3) They think they can lot and then find out that they can't and feel stupid lol

Basically this. They succeeded, but that's not enough. In the current system they're able to make others fail, and so they do.
I always register for duty completion to avoid this.
