Crests not as useful as ilevel when looking at upgrades

crests not as useful as i-level when looking at upgrades. I find narrowing the diff’s more useful in choosing specific items to upgrade.

Could you perhaps expand on a particular example or use case that you have where you found the previous max upgrade level more useful than the new max upgrade threshold?

I can limit the value of lower items I might want to upgrade to better compare with items I already have,so say a 600 item with say 610 one.
