I ran out of space years ago and have since

That hurts a lot :(. I ran out of space years ago and have since just trashed all the cool items I have come across over the years. Trying to juggle a dps/prot/pvp set some seasons, po world of Warcraft plus mats etc, I had run out of space. I was hoping that the system would know what we had attained over the years and auto populate the toy box tab :(. Any news on whether we still need to have held onto the item or not? Would appreciate any knowledge on the fact from a blue if possible :).
