Equipment from Gachapon Guaranteed Above Average

Since a lot of these items are farmable without Gachapon, it often feels a bit unrewarding to get them from the Gachapon, which doesn't help when you're the human equivalent of a broken mirror and always get the lowest rolls possible, so i think it'd be a nice buff if Gachaponed equips were guaranteed to be above average. For example, a Maple Glory Sword (one of the many maple weapons in the gachapon pool), 81 average attack, 78 to 85 roll, it should guarantee to atleast 83.
