Just optimized for “best in bags”, and the addon told me to replace gems. The mastery gem in my legs should be replaced by a haste gem, and the haste gem in my ring should be replaced by a mastery gem.
This seemed like a weird suggestion. Why would you swap gems?
While the gems may be exactly the same, but in different items, you can override the gems with what you currently have to ‘cheat’ the optimiser; what may be at play is that the the secondary stat’s on the individual pieces carries a higher priority for gemming, to match any algorithmic results, but leaving the nett result the same.
If you press the “help” link next to the big Best in Bags section header, then click Create Support Post, it will generate a snapshot ID for you – copy and paste it in a reply here. With that we can see your exact setup.
We have code to check for net-zero gem changes, but it’s possible that a case is slipping through. It is more complex than you would think.
