how could your ls force you to give a piece of armor to someone else? they cant even see what you got unless you could put it in a pool. and then you can still just take the armor, its only so if you already got the item you can share.

the thing is many people continuously receive the same armor and no one else gets squat. now if there's some hidden system that's rewarding players for their effort thats one thing. but as far as it seems everyone gets the SAME drop chance. everyone shares light% and Treasure hunter increases. the only way to upgrade your lights is by having everyone work together (there are procs ranging from elemental magic to dragoon breath attacks, to tomahawk from warrior).

so as it stands tons of loot is just dropping to the floor. and none of this armor is NEEDED to do voidwatch or any other event/nm. so your LS being greedy and forcing you to give them the good drops has no bearing. no tank will be saved by this armor and no DD will do 10k ws's because of it. your system doesn't seem something easily implemented into FFXI either. not a horrible idea i just dont see it happening.
