I really agree with OP. I feel like there is an endless sea of common and uncommon items, and a few rare items, which everyone seems to have anyway. The Mythical ones should REALLY step it up a level and add effects and other things that lower items don't have. I was really excited when I saw that the new Int chests had 2 different mythicals in them. Though I do enjoy the design of them, they aren't at the same level as the first 4 mythicals that you named.
