That said, the Vault is a PvP item.

Packaging the crates with it to get PvE players to buy the feat is bizarre. Literally who cares if someone in a PvE game spends those points?

For them to be functional decorations they would need to function on a level at least as good as the already available options (in the world of storage, good being defined as a combination of footprint, materials to make, and slots available).
Otherwise, this one considers them malfunctional.

As in, maliciously functional.

Trap choices aren’t cute in any feat tree.
