right now items on the ground look like:
[o o ITEMNAME o o]
where the o’s are the dots from the affixes.
Just make it like
[o o ITEMNAME [12] o o]
Where the [12] indicates the sum of all present Tiers of affixes.
This number should be turned off by default. There should be a loadingscreen hint that one can turn this option on inside the gameplay settings. Reason for this is accessibility: For new players this feature is practically useless and unnecessary interface clutter.
I also think that this is actually better than having a new lootfilter rule (to filter for sum of tiers). But those two things could also be present at the same time, they don’t exclude each other.
