I can dock; I don't need to learn, that's not the point. I find that auto-docking gives me a much needed break (so I can close my eyes), just like supercruise, or jumping between stars. It causes me physical pain (in my eyes) to stare at a computer screen without interruption. It's one reason why I play ED, instead of other games. Of course, "every second" doesn't need to be fun. I'm an explorer at heart and am used to the grind. My other main ship is a Python, which is what I use when I need to haul more cargo. I'm not a fan of the Anaconda, I find the large-landing-pad requirement to be too limiting.
I collect a lot of scanned data, even in the bubble. It adds up, especially when submitted for a CG. I recently omitted the DDS to make more cargo space, but then I needed arsenic and couldn't scan to see if it was available, before landing with my SRV. What a pain.
Which is exactly why a DC shouldn't take up a cargo slot.
I can understand where you are coming from. However, I would be remiss if I didn't remind/inform you of the fact that DCs do fail at docking sometimes. I once had it mess up on me on 3 consecutive docking attempts. I also never said that you needed to learn, I just mentioned what I used a DC for. My point, if there really is one point and not a bunch of them, is that a huge deal is being made out of one, small, and relatively inconsequential thing. This game is based on trade-offs. You want your ship to dock itself (most of the time)? Then you have to sacrifice an internal slot for it. You want to fly a big ship with lots of slots and weapons? You get to sacrifice a lot of credits and time for it. You want to be able to recharge your shields really fast? You get to deal with a massive amount of heat for it. It's a part of the balancing act that is at the heart of this game. Sure you could fly a sidewinder forever, and pay diddly squat for insurance, but you would also be very limited on what you can and cannot do. Having your ship clearly is something you want to have. Well, there is no such thing as a free lunch. Got to pay for it somehow (and not just in credits).
