That’d be great, if the illusion system worked on placeables. But it doesn’t.
Placeables should have the same functionality of their counterparts: same storage for the same cost of creation (if it costs the same as a large chest, it should have the same slots as a large chest at the very least).
Armor and weapons? Sure, make them illusions only. If the devs want some gear to have the same stat lines they’re putting on some of these Bazaar pieces, rework some of the existing armor in game. We have plenty and they’re all visual and very few have different stats. I don’t even bother to learn most of them because it’s all the same.
