easy example: guess how many good levelling builds utilize MIs these days
as for my own; i usually use even more since i know how/where to obtain them and like to level meme builds, like fire ABB using ugdenbog rifle+vilgazor necklace and ilgor medal +solael legs and ofc viloth rings for extra points
like i said, it’s literally the simplest of concepts; if all you cared about was the affixes; you could use commons or craftables and it would be the same or even better (since craftables get bonuses too ofc)
The reason MIs are chosen is always because they bring us a base bonus that is good to a build, be it during levelling or end - and ofc the modifiers can be straight up build defining or rival or be better than legends (if they didn’t have those modifiers on certain slots you’d see lot less MI use “as was the case prior to patch 1.1.5”)
