I somewhat understand why the op would ask for such a thing. When theres loot involved some times "training" takes a back seat. Even if the event/fight is about training before it even starts. eyes turn green and then folks can get butthurt if theres no wins.

By removing the reward at then end, and removing the gil sink of repairs, it makes such a run leave no doubt tht this is for training new/inexperienced players ONLY. SOme folks would want nothing to do with a run with no loot, training or not...but then you do kinda find out whos hepful for the sake of helping, and whos really after loot alone, no matter who is left behind.
