Would have been good if fdev added ultra rare drops
There is one... its called Titan Drive Component, lol.
TDC are preety much one and only "ultra rare" drops on titans remains - and can be consider both as trophy and something that have actuall use...
Selling such might be viable "carrer choice" for some, I recon its about 30 millions per each, still would find buyer or two in any time as there is quite demand according to Inara - but no one sells it right now, and when does, I can safely guess its selling fast.
Thats it, until once corrosive gas wears out, the spawn rate of TDC, goes down by a lot, and by with it, fun factors went down as well, and spending hours to find only one or two, just to sell it later in some random FC, its not really efficent at all, far as "profit per hour" concern goes.
Majority of cmdrs who finds it, rather keeps them for themselfs to trade for those juicy FSD's, especially with current drop rates.
In "fresh" titan remains, with corrosives being still active, I could find one every 10-15 mins, and fill entire size 4 cargo rack with those, in like 2-3 hours. Spending few hours in such, would always yield several TDC's in cargo hold, and it was quite intresting "salvage" experience, because being in caustic cloud all the time kinda forced to collect and use those caustic sinks and refills, wich made entire thing felt more meaningfull, and had that real "hazardous" vibe about it.
And yes, there was not as many npcs around (atleast in Cocijo) who would clutter scanner and local (chat) feedback, but in older wreckages thargoids could spawn in, but that no longer apply, since they left bubble for good, it seems.
Now? Ever since gas faded out in last titan, Cmdrs can consider being quite lucky if finds just one of TDC's, in within 2-3 hours of flying around dead titan.
From fun and quite intresting, it went to straight up boring chore, that is to find TDC's now in those remains, and whenever another cmdr appear in same instance, the amount of npcs seems to double... the only good thing from those npcs that sometimes an wanted conda or python shows up, so atleast there is something to blow up, out of straight boredom (apart of other cmdrs of course

)
In anyway, that Galnet article, kinda was late like 2-3 weeks. But I guess, better late than never.
