My personal opinions about legendary gear is that it should be rare. I believe that giving them out to everyone just makes them epics with a different color. Now not being an elitest and saying only mythic raiders should get them or anything, and I definitely wouldn't want them tied to rng, but I was thinking about a different idea.
What if legendary gear from now on was released one piece per armor type each tier and involved doing a long quest chain that involved doing some reasonably challenging group content (final boss of a heroic raid, or +15 key), but at the end required you to complete a solo challenge that was on par with the mage tower in difficulty.
This way it would truly feel like legendary loot is earned and not just given away for free or tied to rng, and would still be within reach for non mythic raiders if they had the skill enough to complete the solo challenge for the tier.
So what do you guys think about this, got any ideas of your own? Please share them.
