1) Cargo can't go spinning off if it's sitting on the ground and has that friction to deal with.
On a sidenote - according to my own observation in Odyssey it's far easier to move/roll - on-foot - cargo on the "natural" terrain than on the artificial flat surface. Counter-intuitive, yes
2) Ad hominem attack, going after a typo or word choice because you don't have any debate points?
Even the mere idea of an attempt to direct my attack on typo/wording would be quite dumb from my side as I'm not a native speaker, so no, no attack intended - sorry if it can be taken like this - the idea was only to underline that we are speaking about 100 tons of cargo, and if the weight can be times less on a low-g world, the inertial mass is still there
2) SRV picks up 2 at a time, transferring large amounts of cargo via SRV gets REALLY annoying, really fast.
Yep, I do know this pretty well. Probably transferred by this method more cargo than the "average" player. But except some rare occasions like some, imo, not really well thought ahead CG's (that do promote relogging as well) like the recent one there are no big reasons to practice this in game, except the players own will and RP reasons.
2) Limpets don't handle planets. They SHOULD, but they don't.
Honestly I've never heard any official statement that they should handle planets. However, even that they should not, on special occasions and using special techniques they actually do.
You've seen those sites with a few cargo cans, right? 6 or so maximum usually? Now, if ANY ground activity is EVER going to be lucrative and involve cargo containers, a method of moving cargo is going to be needed. Moving 2 at a time in an SRV is tedious. Scooping them is clumsy. Adding ANOTHER suit seems a bit much, if it's a rifle slot, you can easily make a loadout for it.
Yes, few hundreds of those sites. 6 canisters = 3 SRV runs. There are sites with two times more canisters, in fact.
Moving - yes, tedious. Scooping by the ship - yeah, but could be fun sometimes.
But once again - at this moment I'm not aware of any in-game imposed reasons to do this. Lucrative ground activity? Hmm - do you mean you scoop/tractor beam things on one site, then travel to another and repeat the process? Probably the travel time will be bigger than the tedious srv transfer runs, or...
Or do you refer to the relogging on the same site? And repeating the process indefinitely? And this naturally will work both with commodities and materials (hello, Dav's Hope)?
I can only assume that probably that kind of the game simplification that do promote relogging is not the priority choice for feature development?
Besides I understand that harpoon and "winch-like" devices also have been requested quite a number of times for spaceship piracy, for example.
When it comes right down to it, though, I think this is all a distant second to just handwaving it away as "using guardian tech" and adding tractor beams to cargo scoops, and putting them in another core slot.
I do not really oppose for tractor beams or relogski. That's imo a question of personal choice. However I'm not sure that these kind of devices have appropriate lore background (don't quote me on this - I'm null in the Elite lore)
