It's not in any way essential for me if the development process of a game takes more or less time. Even if I like the game very much. There is no "too much patience" in this case because there is no consequence for me.
Also, concerning development time, I believe Frontier wants the same as we do, to develop as fast as possible. So even if something went wrong and they needed a lot of time to, for example, restructure something under the hood or whatever, that's unfortunately but well, can't be changed.
You can complain about things taking to long and you can also choose to not trust the devs to love and support the game as good as they can, but that's your choice.
Given you complain, what's the outcome? Let's assume the devs don't care and ignore you, which would mean, the outcome is nothing. Let's assume the devs care, but ran into problems that will take a while to restructure, and because of complains they rush. Rush is never good when coding. So they see the complains and don't rush and take their time because it is necessary to create a clean update they can build on later. So, again, what does impatient complaining help? I tell you: nothing.
Perhaps "Trust" would be another topic that deserves a thread on its own. But to make this clear: I trust Frontier to be as eager as we are to get new stuff into the game. I think Elite is a labor of love and they do the best they can, which is, in my opinion, pretty awesome so far. You can believe what you want of course.
Excellent example! Don't. You go somewhere to find this one specific USS because you want something fast. And of course it will not come fast enough because you are impatiently cruising along and waiting for it. Instead do something else and scan every USS on the way. The one you are looking for will pop up at some point. Yeah, perhaps not today, but well, that's what I am talking about.
