With the recent launch of patch 5.1, we have added support for epic item upgrading to our Loot Rank
You will notice that epic items have three versions that will show in the ranks - a non-upgraded item, a +4 ilvl upgrade and a +8 ilvl upgrade. The upgrade items will be denoted with a green up arrow and the level of the upgrade (L1 or L2) in the 'Item Level' cell. The Valor Point upgrade cost is also shown. The item tooltips also show the upgrade level and upgraded stats.
We will run this system as a beta over the new few weeks. Please report any bugs you find in our bug forum.
* The ability to switch off item upgrades
* Correct detection of upgraded items when importing a character from Battle.net (waiting on a Blizzard API update)
