Gamers are a spoilt bunch these days, they seem to want everything instantly, everything seems to work like this now, press A to blow up everything, press X to pick up silly overpowered weapon, press SPACE to collect insane amount of cash, press UP to watch your character climb a building with little to no interaction from you. In a game that is designed to be completed in 1 sitting this is all fine, but I don't think that Elite is supposed to be that game, in fact I really hope Frontier dont listen TOO much to the whiners otherwise Elite is going to lose all the things that make the game what it is.
I dont understand what the big hurry is, and I don't see why people need to know everything right from the start, there is a lot of fun to be had just learning how things work for yourself. 1 post I read recently complaining about how you have to swing around and make another try if you don't slow down in time when exiting supercruise, I mean really, from the time you overshoot to the moment you've come around and are within the correct range to drop out of warp is just a few seconds, if people don't have time to play video games, they should not play video games.
Obviously, its ok to be angry about broken stuff, things that were promised and are simply missing, things that break immersion and tedious things that do not seem to have any reason for being there in the first place. But there is a right way to complain and the annoying way. Some gamers are quite young and they don't know any better, but the very best way to get the attention of the people that actually make the games is to make a constructive post explaining the problem in detail and perhaps even give an idea or 2 as to how this issue might be fixed or tweaked. Be a part of the solution, not a part of the problem
I'll close with a tip: (spoiler alert if you want to learn how not to overshoot when trying to exit supercruise on your own, haha)
After a few tries I've discovered that going full throttle when in supercruise until the moment the 'ETA' indicator reaches 7 seconds and then slowing down and maintaining 7 seconds without going below 7 works best and you will never overshoot your target again, you can bring it down to 6 or 5 but you start risking an overshoot. It was fun to learn this my way. But if Frontier absolutely have to make any changes to this then maybe they could add an option (not in by default) that turns the timer green or red when you're at the correct speed or going too fast.
