Improve the drop rates of lower and mid level unique and set items at normal and nightmare difficulties, that way we actually have a chance of finding these items at the start of a new character. The high tier item drop rates are fine, as they should be hard to find.
While the last rune drop buff was a vast improvement versus what it was, I don’t think it was enough. While I feel the last change to the rune drop ratios is mostly OK, I think the overall drop rates for runes is still too low and could use an overall boost of two to three times more often.
The gem requirement for cubing runes is annoying and should be removed.
These are very easy changes to implement and should at least be considered.
