I suggest a bind on account purchasable large/huge collectible bag. Plat or DDO points.
Lots of permadeath players treat characters as independent entities, trading nothing with other characters. Some active PD guilds even use that as a rule. Sadly, this limits the amount of collectibles they can hold. Because we reroll characters upon death, bind to character bags are not a good option. We would like a large/huge collectible bag that we can buy (plat or DDO points) that can be heirloomed to a reroll. This would allow players who like to collect an opportunity to do so within the spirit of independent gearing.
