Wow. Ok, 3.0 introduced a lot of major changes - total revamp of engineers & mat/data inventory, new mission reward system, wing missions, etc. Of course there are going to be unintended bugs that need to be fixed. Were you here for 2.0 and 2.1?
But let's address some of your points:
A list of things I have observed since Beyond released:
So... apparently passenger missions have been nerfed after they were "tweaked" after the whole Quince issue. Great. Passenger missions suck now. Boy, traveling dozens of thousands of light years for 5 million credits is such fun. Yes, I actually saw a mission payout with that number recently. No, I do not have a screenshot. I never bothered with those missions because it's just so much fun to go around a sun and hit the J key for over an hour. And then you have to go BACK.
Yes, well LONG distance passenger missions have always stunk. Not sure why anyone wanted to do them. VIP tour missions still pay well, I think, and are a lot of fun. The bulk passenger mega payout needed to be fixed - sadly, this meant a massive drop (too much) in pay until they get the algorithm fixed.
BGS decided tons of skimmers needed to die. Whoops, new system backfired, better remove the skimmer missions entirely.
I'm sorry, but these missions were a joke. Forget the stacking for a minute... why should you get paid 5 million credits, in one mission, to kill 8 skimmers? That takes no time at all in SRV. Worse, the system was letting people stack a bunch of these and blow them up from their ships - moving back and forth over the same base to cause respawn - to cash in quick. If you can't see what's wrong with the risk/reward there... wow.
Whoop, mining missions started paying a bunch. Better remove those.
No, they removed those because the alternate reward system was giving people the option for a BUNCH of ore, which they could then turn around and use for a mining mission turn-in. There was a video which showed how a commander could sit in station and just keep turning in missions and making money without ever leaving.
I'm sad that they totally removed mining missions, as that screws over miners (who have it bad enough already). I don't know why they couldn't just remove mining missions that used the ore from rewards (I've only seen about 4-5 different types offered) and leave the rest in. May be a coding issue, or maybe there are even more ore rewards I haven't seen, I don't know.
Reward system gives more rank advancement. Gee whiz, I'm sure data and donation missions are next.
Maybe. If they want to keep the grind the same, I don't know why they can just divorce reputation per mission from rank gained with said power, and just have a flat rate per mission. In any case, this is a result of the new mission reward system, which gives you a choice, and is a good thing in of itself. Unfortunately, it's lead to undesirable side effects.
New C&P kind of makes smuggling and assassination pointless.
Nope. Not even close. True assassination missions (e.g. Kill Pirate Lord) are legal and won't make you wanted. Also, any kind of crime that doesn't give you a bounty (trespassing, weapons fire, murder) can be cleaned at the very station that has "anonymous access" due to your fines. And if you do have a bounty, providing it's not murder, you can quickly clean that at Interstellar factors. Heck, Planetary scan missions have become much nicer for me this way... I just do them in all the target systems, then go to an IF system, clear the tiny bounty, and then go turn them all in.
If you murder someone, you do have to wait 2 hours. However, that's a far cry for the 1 week you had to wait before. Besides, you can always go to an anarchy system where they don't care about any of that stuff. You could even transfer a clean ship there, if you want, switch to it and continue playing ANYWHERE while your notoriety ticks down.
KWS updated and- oh, look, bounty hunting is even less profitable. Hurray.
We complained about this in Beta. To my surprise, Sandro responded very quickly and there was a very interactive dialogue that went on for at least 2 weeks before 3.0 went live. They could not implement those changes when 3.0 went live, but it's coming soon in a minor patch (supposedly just a few weeks a way). And that deals with rep! I still make nearly to as much $$$ in the current 3.0 system with, or without, my KWS as I did in 2.4 with it. So I disagree with you on the cash loss. But even if that's the case, the solution is coming.
I'm no white knight here to defend the devs, but I seriously don't understand the outrageously large amount of whining after this patch. If there are issues right now, and you know they'll be addressed soon, take a break from the game OR do something else in the game. Geez.
