We need a way to filter on the exchange site based on the tier of the attributes and not just the sum.
For example: if I am looking for a Quarterstave with % physical damage between 55 and 94, and I want this to be a single tier 9 attribute, giving room for a substantial improvement in crafting, but instead the sum of 2 equal stats from different tiers that are also located in the range appears, for example a % physical damage tier 4 and another tier 3.
or am I wrong?
