Now, don't hate on me for saying this but:

The best solution is to just not use quartermaster. It is better to just tell people to lot/pass on things. This is generally accepted and the only reason to use quarter is you don't trust anyone in your group- but if that's the case none of them probably trust you either and probably wouldn't join a party using quartermaster in the first place.

I had the same linkshell for a very, very long time. We never used quartermaster. If a drop was for a specific person, they would lot it and everyone else would pass. This also helps avoid inventory related issues, as someone can hold on passing if the person needs to free inventory space so the item doesnt fall to the ground.
