These items already have an item level. How else would would the desynth success percentages be calculated? I see no reason why it wouldn't be considered "proper," or how it would affect you personally. Besides, having an additional star rating may cause come confusion, since recipe levels of 50+ already use a star system. However, I could see the level 50+ items using stars, to match up with recipe rankings (assuming the items didn't come from a star rated recipe).

I am also aware of referring to other logs as reference. I just made the suggestion to possible save the player some time. The data is there, I would just like it to be displayed, in the item description, for quick reference. The current alternative of going back and forth, multiple times, gets a bit tedious.
