Why are there no mythic boots, pants or shields?
I’m glad there aren’t more Mythics. Heir of Perdition, Ring of Starless Skies & Shroud of False Death are in most of the builds already–we don’t need more slots being taken up by Mythics.
I think they should add boots, pants and shields to give us a little more variety and maybe a few new skills/powers. A solution to your issue might be to limit the number you can equip at any one time.
I like the idea behind rare mythic items very much. I want to see a Stone of Jordan Ring and some other memorable or nostalgic items from previous Diablo entries to make another appearance as mythic item.
However, since build defining unique equipment seems to be gone with the next skill trees, there will be a lot of new space for purple equipment. To the benefit of the upcoming leaderboards and also for current & future itemization options, it sounds like a good idea having a limitation on how many Mythics can be enabled per character. I hope the D4-team is aware of that.
I think that this may come in the new expansion, since they have removed all passives on the skill tree, the shroud is no where near as powerful as it is/was
