I am being told that my best upgrade is +3.84% (200 ilevel from N Nathria), even though when I look it up in the upgrade table for Normal Nathria, it’s only 0.09% upgrade. I know the calculations are different between the finders, but I think the great vault one seems to have a bug. The item it’s recommending is only 3 item level difference, with a minor delta in stats (+2 Intellect, -2 Haste, +3 Mastery).
For now I’m going through the work of looking up the upgrade values from each of the upgrade flows other than “great vault” calculator.
I’ll take a look – I was able to reproduce the issue with delroth’s snapshot. This is a new kind of ranking (required some fancy code to make it perform well enough to do more thorough optimizations of every single item in the list), and it ran into some issues with unique constraints in some cases.
