1: I'm still curious about why you think the average skill level of rebel mechanics would be low.
2: Look at most of the Imperial leaders we see in the OT. Are they worried about hunting down the rebel manufacturing centers or are they worried about finding the HQ? And these were the high level commanders of the Empire's forces which means their focus will determine the primary focus of the Imperial fleet.
3: Some people think that a factory would be easier to find then a HQ because there is more ship traffic in and out of it. While the latter part is true an HQ is putting out a lot more signal traffic then a factory would be so I'm not so sure about the former part.
4: The matter of resources for the factory or shipyard. Its possible for Rebel front companies to buy resources, uncharted mining colonies could be allied with the Rebellion (Remember that Cloud City was either unknown to the Empire or considered to small to be worth bothering with before Han flew there. Also Admiral Ozzel mentions that there are a lot of uncharted settlements out there early in Empire Strikes Back.) and of course they could raid Imperial convoys and Imperial allied mining centers for resources.
5: Now for machinery for the factory or shipyard. We aren't sure how much machinery is needed to produce military ships that isn't identical to machinery used to manufacture civilian ships and can't be adapted from machinery used to manufacture civilian craft. Any civilian machinery which can be used or adapted can be purchased through front companies. Any military grade only machinery could be bought on the Black Market, manufactured under the table on friendly worlds. seized from the Empire, or possibly salvaged from abandoned CIS shipyards.
Also IMO it is absolutely vital for any group that wants to be seen as a credible military force in Star Wars or any similar setting to be able to manufacture its own starships, Without ships you can't win a large scale war in such a setting. And while you can capture ships or purchase them from the black market or third parties sooner or later you are going to want a more reliable source of fighters and warships which means production centers your forces control. It wouldn't surprise me if one of the first things the leadership of the Rebel Alliance did was start projects to gain control of or establish Alliance controlled ship and fighter production centers. If the B-Wing in Rebels season 2 really is the prototype then the resistance network already had both fighter design and at least some fighter production capability at that point.
1- Hard won experience with reality.
2- The movies are about the heroes - who are high ranking members of the rebellion. Obviously tracking down the rebel leadership is going to be a thing. For much of the Star Wars movies, the Empire's leadership (personified by Darth Vader) is more interested in tracking down Luke Skywalker than in tracking down the rebel's leaders. But showing Imperial leadership wanting to destroy the rebellion's logistics would be akin to focusing on the CIA's efforts to track down al-Qaeda's funding in Zero Dark Thirty: It's simply not relevant to the story being told.
3- A factory needs bulk freighters laden with components and materials. An HQ only needs to dispatch and receive courier ships and can use those courier ships to send and receive messages both physically and electronically.
4&5+ - Absolutely. However, the B-Wing appears to be a hand-built one-off. It is entirely possible that the rebels did not acquire their own means of manufacturing starfighters until around or about the Battle of Yavin (or even later if X-Wings are a commercially available update for the Z-95/ARC-170) and did not acquire their own means of manufacturing capital-class starships until around or shortly after the Battle of Hoth/before the Battle of Endor with the liberation/independence of Mon Cala. This was certainly the case within the Legends continuity.
Given how early we are into the rebellion in Rebels, I think it is unlikely that the RZ-1 is not a commercially-available starfighter: All the other rebel starships seen thus far are either commercially available vessels (VCX-100 light freighter, CR-90 corvettes), military surplus (Pelta-class frigate), or captured Imperial materiƩl (Sabine's TIE Fighter, shuttle).
1: I'm still curious about why you think the average skill level of rebel mechanics would be low.
Me too. Source material tends to paint the average Rebel anything to be more skilled than it's average Imperial counterpart.
The Empire generally makes up for lack of talent with overwhelming amounts of stuff. Why have 1 genius engineer work on something, when you can have 10 mediocre engineers do it instead!
You mean like Raith Sienar?
In the Legends continuity, virtually every Imperial engineer is a genius. The rebels don't have such a level of individuals in their employ outside of the direct action and political/diplomatic sides of the house.
The brilliant thing about Imperial logistics (just as with most modern logistical organizations) is that you don't have to be brilliant on the technician's side, just competent - the brilliance can be left to the engineers (of whom the Empire has no shortage). There is a good reason why modularity is a big thing in both modern militaries and with the Empire. The rebels would be wise to copy that capability.
I don't get it. Why do modern works have to conform to old forms of lesser canon (he works siting the RZ-1 as being post Yavin were pretty far down on the old canon list) especially when a new canon policy has been in effect for years at this point. The A-wing was chosen for Rebels because 1) it had a cool Mcquirre painting and 2) people familiar with the films would also know what they were and 3) saved on having to design yet another new 'old' ship for the rebels to fly. He last point is worth remarking because the production team does not have an unlimited time to crank out episodes, and any new ships risk backlash from uber nerds where old ships are established and accepted.
Could have been worse though. They could have been flying E-wings (didn't they already do that in the Yoda Chronicles?)
The point is that it would not have been hard to keep us all happy.
But no. Out with the old and in with the new.
Lucus thought that it with the PT and we all LOVE those films don't we lol
I'm guessing this is sarcasm, but in the event that it isn't:
It is literally (not figuratively) impossible to keep certain segments of the fandom, any fandom happy. Chiefly because certain segments of the fandom love nothing more than to complain about things. I suspect that this is not because there is anything to actually complain about of any import, so much as a basic instinct among some people to complain about anything. Even when that anything amounts to little and less than nothing.
