The Auto-loot system in general needs a ton of work.
These drops are the only reason people are OK running these old ass Urgents - if you remove the drops, it make these "new" content completely worthless to run.
Define "these drops". Some of this topic's posters have separated out the weapons, the units, the Add SGA items and so on. If you remove all the drops from any quest it'll be worthless so that's a bit of a void statement, but even entirely removing just the weapon drops (since those are what get cubed in the first place) would still leave two good reasons to keep running Cradle UH in the high-slot units and Add SGAs.
