IMO , drop rate of totem should be 100% drop for 1 run
but not to all ppl in party but just for 1 person
means 1 totem for 1 runs
( not to make it too easy if it drop to everyone)
and if you're lucky enough it will drop more than 1 totem for 1 run
( to others or maybe same person )
and if you're damn lucky you'll get weapon.

About duplicate items make it no drops to someone who already got it and have in inventory
or maybe make it not drop to self just put it in loot that way will be easier.

I do Ifrit over 200 runs and get all weapons 7/7 before Moogle is coming ( never use totem )
I do Moogle for about 100 runs and get all 7/7 weapons without using nutcharm
( while 1 guy in my party get 7/7 within 20 run )

I wonder , while someone can get over with why the others still complaining.
