people have been bitching for ages now about some items, like bags and suhc not being account wide. Seems that the Accounting dept / devs had the impression that this feature was in AOC (as usual they saw it in TSW and assumed that its everwhere).
So now thanks to Nusquam and much complaining they are finaly putting it in, hopefully on Bags next.
Although to be honest this should save space for you vanity lovers, instead of storing, just delete and reclaim when needed. Only need to keep stuff thats not infinite claim
