Once you have a level 20 enchant you can't see what else is recommended. It would be great if we could see enchants of equivalent and even slightly lower level even after we have 20.
The most obvious case in which this would be useful is in the case of hit rating enchants. Below hit cap these may be BiS but when all the hit is above and beyond cap it becomes WiS . Even a low level str enchant would be more beneficial. I would like to be able to see what my other options are.
