This was expected as far as I was aware, so not a surprise. I want something more complex, but I assume it will be along the lines of what was in the playtest.
Rarity
Magic item rarity serves several purposes in the game. An item’s rarity provides a rough measure of the strength of the magic in the item as compared to other magic items. If your campaign allows for trade in magic items, rarity can help you set prices for them. Rarity also gives you a sense of how likely characters are to find a particular item, given the characters’ level. All that said, rarity shouldn't get in the way of your storytelling. If you allow a ring of invisibility to fall into the hands of a 1st-‐level character, then so be it. It might be an enjoyable feature of your campaign.
A magic item has one of six different levels of rarity, from most to least available: common, uncommon, rare, very rare, legendary, and artifact. The closer an item’s rarity is to artifact, the less numerous such items become. Most legendary items and all artifacts are unique.
