Let me start with the basic part of my suggestion here: give us a way to see the range Implicits/Crafts can go to. Like, pressing alt shows what is a prefix/suffix, but have it also show the possible range. So we can have an idea how good the drops actually are. (If there is already a way to look at this, someone please tell me, this is killing me.)
Second, and again, as all my suggestions, I know this isn’t the final build and I expect A LOT to change before then, but just in case: rein in some of the values in Implicits/Tier ranges. While running my Shaman I had one monster drop an Imperial Greatsword with +57% minion damage implicit and another drop the same item with +11%! That’s absurd level range for the same drop.
