I've seen a few other posts about percentages and the way upgrades are displayed and I have a suggestion.
Would it be possible to rank both the total upgrade (as it is now) as well as the upgrade for that specific item slot?
Example: 890 ilvl boots. You see a 915 ilvl boots which gives you a 0,50% total upgrade, but for that slot it's a 25% upgrade in dps.
Think that would help in visualising upgrades now that the numbers are so blown out of proportion, as it's really hard at first glance to judge if an item is worth (bonus) rolling for.
This goes for sockets, enchants etc. as well.
It shouldn't be hard from a technical point of view to add as it's just a little math
