So How Are We Supposed to Get Platinum pool again???

Hey Kabam, just curious behind the logic of this Platinumpool bundle. For those summoners who already had the Left Arm and other 3 pieces, how is wasting nine thousand 5* shards for a duplicate item we can't use beneficial? Will there be some option to trade in duplicate pieces for the 1 missing item? There is a 100% Chance for units and a 1% chance to acquire a piece of the Pool and you can only purchase 1 bundle. Unless Im missing some details thats an impossible chance of actually getting the needed item! Someone please help explain the logic to me.

2) there is a chance to get the extra pieces in the crystals.
