We have been here before (& I’m sure many other threads/posts). Though you are at least taking a different spin on it.
I suspect there’s not anything that the community can do to help given that it needs to be coded & they’ve already got an idea of what they want it to look like (though I can’t find their post), it’s going to draw more from Grim Dawn than PoE. Though they did say that it would be a tiered system, so if you had one rule that said “don’t show me any Burning Branches” but above it was “show me anything with a T7 damage affix” & a Burning Branch dropped with a T7 affix, then that item would be displayed.
So hopefully we’ll be able to include or exclude drops based on the specific affixes they have, their bases & ideally the number of affix slots free. And quality (ie, uniques/sets/legendaries).
Edit: Found it, it was a quote from discord, not a post per se:
Edit #2: It would be nice to see what it looks like though, so we can give some feedback.
