Some classes (such as any class capable of using staves) are unable to acquire a good deal of items shown to them through ATT. For instance, my Hunter is shown three weapons that Hunter Vivanna drops: All three are intellect staffs, which cannot be obtained by him no matter how hard I try.

Would it be possible to add a toggle to prevent showing unobtainable items?

That's effectively a "Personal Loot" filter, which we had in the past. Unfortunately the filter was significantly more expensive than we tend to allow and had a lot of inaccuracies since the data provided by Blizzard is unreliable and incomplete as well as being behind a slow API endpoint.

Sadly a filter like this is not realistic. You'll need to make alts if you wish to completely 100% the zone.

Fair enough. Thanks for the response.
