Upping Droprates on Corrupted Bosses

I’ve ran several corrupted maps with varying rarity since their introduction and I’ve only gotten one of the uniques from those bosses. Should the drop rate on these bosses be upped? Or maybe tiered like Xesht drops where you get a guaranteed unique but the better ones are rarer?
