Since yesterday this is the standard drop for Elite STFs:

2 EDCs
1 Prototype Salvage / 1 Rare Component / 1 Prototype Component / 1 Random Mk XI/XII Item (Usually Deflector / Engine / Shield for space, I got a Shield once in ground ) (Purple or Blue)
1 Tholian Lock Box.

This is not worth it anymore. You used to get An extra item because the Lock Box did not count as an Item. Its Absurd and needs to be fixed IMO.
