I'm in the process of trying to clean up my copies of the data files (which appear to have picked up some junk from loading characters) but which also seem to come with a fair amount of junk in the default files. Since I'd like to not have to do the
cleanup with every new release, I'd like to get some of the junk removed from the default files. But that requires some consensus on what's junk and what isn't.
Here are some of the categories that I'd like to see if others also consider junk to be removed.
Items that can no longer be obtained e.g. Older season PVP weapons, one time world events that are over.
Items with an item level below 200 i.e. less than T7 or equivalent.
On a marginally related topic, how expensive (in time) is it to process the filters. I notice that there are filters in the distributed default data files that don't "catch" any items e.g. most of the non-heroic dungeon filters. If
there's a time penalty during optimization or build upgrade list associated with processing the filters, then maybe those should be trimmed down as well.
