I wouldn't say it was hate, I would say that after a year long run on massively inflated prices, it's funny to see people getting mad about it as though nothing was wrong before. A bit like watching the Yuppies' in the late 80's when out all went wrong and they were crying into their Filofaxes. Maybe that is just my spiteful side coming out.
The problem there is, if you just flatline all the prices, then you have no special commodities. Water is as valuable as LTDs, that seems silly. LTD's are supposed to be rare, hence the high price.
Realistically, (I'm making the numbers up because I don't know), if your FC can carry 25k ton of cargo, being able to fill that with LTD's is silly. Hardly rare at all then. So they should retain a higher price than water but be rare to find. So as you go out in your carrier, over the course of a month, you might be able to make a billion with LTD's, not one session or a couple of nights. What people seem to want, be screaming for, is for them to be very common and very valuable. Makes no sense.
If you like the gameplay of Deep Core Mining, then it doesn't;t really matter what the profits are, does it? So long as it pays a reasonable amount, you're having fun. It's the same for trade, combat and exploring. None of them are 500m an hour sports but loads of people love them and do them regardless of th profit margin, why should mining be any different?
I've seen a few people reference the noob, pretty much stating that they will all leave the game or that they face a grind now. Look at it this way though, right up until the peak of mining, the entire player base had gone through that. No one has the figures but some stayed, some went. I'm guessing the majority stuck with it. Why all of a sudden does that matter? If we all did it and managed it, why won't they? Frankly it rather condescending to think loads of new players won't be able to handle what anyone who purchased the game over a year ago, went through.
In a more compassionate argument against huge mining profits bringing accelerated progress, I think the new player loses out of something quite amazing. I posted once on here about the magical part of the game when you're about 3/4 up the way of the steep learning curve, you're not dying every time you leave a station, you've learned about some aspects of the game, you're on this intermediate level, it is simply one of the coolest levels to be in on this game. By leaving mining in as it was, people by-pass that, they get the idea, are encouraged to believe, that the game is about, getting out of a Sidewinder and into an FC as fast as possible, You're robbing them, IMO, of a great experience, a real learning curve to overcome that results in a feeling of achievement that (again in my opinion), is unlikely to be found, sitting in a ring blasting rocks all night.
