I think there should be two types of loot now that I've seen the personal loot from CLL and DR in Bozja.

You can still roll for the armor pieces in Raids to get the equipment instantly. However, if that fails with you being unlucky that it never drops or someone beats your roll the second loot is a unique coin which you could turn in to purchase one of the loot from an NPC Vendor.

So there's two methods. One the is currently the same for all and current Raids and other to slow build up in case RNG has not be kind to you so you can run the place multiple times. I would love this, because sometimes I do the Raid when I can and the week is nearly over and still haven't gotten the item I wanted so this could alleviate some issues with missing.

That said though if they don't want people to farm for coins to purchase all of the armor pieces I suggest even 50 or so coins and you're limited to one purchase a week or it's treated the same as the weekly loot lock. Either get it as a drop or purchase, but you can't get more than one per week until they lift the restrictions.
