You're correct, I haven't actually stated any reasoning for my opinion that AP could be in the game and that's garbage so here goes:
It's not the time consuming part that bothers me. It can take as long as it takes, thats the game and that's fine. I think AP would be a great feature because travel is a series of spikes to required focus.
If you're making a multiple jump journey, you start by engaging your hyper drive. You hit the jump key, wait like 10-15 seconds to charge your drive, wait another 5 to jump, then hit a loading screen for another 15 seconds. You're literally locked out of performing any other action for almost 40 seconds. Then upon arrival, you IMMEDIATELY need to hit the brakes or maneuver to line up your next jump which takes roughly 5 seconds, wait for any cooldowns, then press the jump key again.
You're essentially doing 5-8 seconds worth of actual skilled work for every 45-55 seconds of travel. 40 seconds of down time leading to 5 seconds of focus, followed by another 40 seconds of down time really weighs on me. It's even worse in supercruise but at least there I can read GalNet or whatever.
I'd be the first to admit I have an absolutely frighteningly short attention span, but I'd also note my internal clock is very finely tuned. Theoretically I'd benefit from 5 seconds of focus per every 45 seconds but instead it makes me insane.
The other reason that I would like to see some AP is because I'm almost always in favor of our ships being more capable. I like the idea of flying fancy spaceships with unheard of capabilities.
