I'm not going to bother quoting every malicious, petty, pointless post in this thread because it would take far too long. But I am going to say this. Calm down. Its just a game.
See, the problem here is that this entire thread has turned into a pointless unwinnable argument. There is no way to ever solve this because its all based on peoples opinions.
To the "Supercruise is perfect". Yes it is. In your opinion. You do not have the right to go around belittling others because they dislike a mechanic that you like, and its incredibly arrogant to assume that you must be right and that everyone else is attacking "Your game" and to assume that everyone who dislikes supercruise must be a newbie who joined post launch. And if they are, so what? These are the people who are going to carry elite forward and ensure that it lasts long enough to become the best space sim in existence! If you are a more experienced player you should be welcoming newbies into the game and answering questions and complaints in a friendly and open manner. If someone comes on here and voices something they dislike about the game, hoping for a constuctive debate and possible solution, only to be met with abuse and rabid "The mechanic/game/balance/etc are perfect AND YOU ARE WRONG!" replies then do you think they will stay, or tell their friends about elite. No, they won't, and elite will die that much sooner. Furthermore, it will discourage people who have looked at the forums but haven't yet posted from joining in. Its fine to disagree with someone, but be polite, even if they aren't. Being polite takes no effort, no extra time and it makes the forums nicer for everyone.
To the "Supercruise is terrible". Yes. But thats also your opinion, and you have no right to say that people who like it are fanboys, or love grinding, or have a superiority complex. They might just enjoy the pace of the game and feel that it works for them. The stuff about being polite also applies. People are mucyh more likely to listen to your complaint if its well thought out, and politely written. In addition, please don't complain about something without posting an idea that you think would improve it. I mean, if you the person who hates it can't think of a way to improve it then maybe its already as good as its going to get. Everything FD does is a compromise. Its impossible to please everyone with one game-why do you think there are so many different game genres? What we can do is discuss what peole like and don't like and come up with suggestions for FD to use to improve the game. And the only way this can happen is if people are polite to one another even if they disagree with other peoples point of view.
EDIT: BTW, this isn't aimed at everyone. Lots of people have been polite and constructive, but some haven't. This is aimed at them.
Now, my suggestions.
As you'll gather I think that "fixing" supercruise speeds is basically impossible. And I can see both points of view. Supercruise is fine in most systems, but sometimes it can take 10 or 15 minutes to reach a station, which is a very long time. I've heard(never been there) that a station in alpha centurai takes half a hour to reach, which seems ridiculous. So, instead of messing around with supercruise speeds why don't we come up with more things to do in supercruise? I think that increasing the interdiction rate a little would work nicely(I realise that some people don't like this idea, but haven't been interdicted in a week whilst in an unarmed hauler carrying various expensive cargos back and forth.) Or perhaps we could have different types of USS. So we could have, distress beacon, energy spike, spacetime anomaly, and have more varied USS(hopefully this will happen at some point anyway as FD have really polished up USS in the last few weeks). Or we could make SC harder. Perhaps we have to balance the gravitational distortion field around the ship for maximum speed, or ride "turbulence" safely to avoid dropping out of SC and taking damage? Perhaps There could be electromagnetic interference that can break the HUD temporarily so that your flying blind?
Its my opinion, but i think that things like these would be a much better way of making SC better than just shortening it.
This post turned out to be even longer than I thought it would be
TL;DR Be nice to each other! And some gameplay suggestions.
