Since when did rare matz started to sell dirt cheap?

I remembered a couple of days ago, I used to sell some rare matz (4* and 5*) up to 15k to 20k, sometimes 25k. Now people are expecting them to buy them dirt cheap! What is this? Wal-Mart? Don't people realize that it is difficult to get forge sparks and grim spark tokens, and it is expensive to buy rare matz with those tokens? Does anyone realize that plasma cells or sun silvers is a super very rare drop? People expect to pay for those matz 500c to 1k, and very rarely 2k. I am serious!
I honestly don't know what happened in those past few days when I was gone! =( Who and what influenced this trend where rare matz are selling down to dirt cheap? I don't get it! I mean I can understand that the price drop on rare matz would go down by a few crowns, but when it drops down to couple thousand crowns, that is just insane!
To add to that...
I find it very difficult now a days to sell recipes and pre-made weapons too, as if the whole player-base in SK already has that item already. I am starting to think that this game is not having enough new players. 0_o
So please tell me, what have I significantly missed from not being on SK for a few days?

You basically have a 75% chance of getting 4 Grim Sparks per Graveyard floor.
So they technically are a common drop (they just about always drop in the same location)
Because with the possible exception of the rare monster drops and the blackened crest there's no such thing as a rare item in this game, as soon as a player can handle tier 3 content, all mats are available to them, all that's happened is that more players are hitting T3.
As far as recipes go, there are just way more people trying to flip recipes for a profit (and performing the largely equivalent but even lower-risk act of selling ports to Basil) than there are people trying to buy recipes. It's an obvious profit-making technique that doesn't require any particular skill or market savvy (although certainly market savvy helps), so everyone does it. Because so many people are willing to do it, the value difference between a recipe's vendor price and the market value of the recipe is no longer very high. It's not that the entire player base has recipe A, it's that every time a player finds himself in the position of wanting recipe A there are a dozen people in trade chat willing to sell it or a port to a Basil with it.
Grim and Forge Sparks AREN'T that rare. I have over 100 Grim Sparks that I could easily turn into a few 5* mats. There's a HUGE influx of people selling recipes, premade items, and also selling teleports to Basil for the recipes people want. Meaning there's a ton of sellers, but few buyers.
Personally I'd prefer if they made it so you couldn't send invites on Basil floors the way they do on JK and Vanaduke floors and took the 5* mats out of the token traders merchandise.
