I absolutely abhor this idea. For a few reasons, one of which is I do semi AFK mine...
The *only* real way to make money in smithing is to mine yourself. I have had many, many in depth conversations about my prices on smithing, to the point that I did raise them because my time is worth something. You simply cannot be a successful smith, and not have an alt miner OR buy ore. Combine into that the highest ore you can mine is basically ONLY mineable in FR (yes, I do know there are other places, but no where you can solo at even 65 and spend hours mining.... yes, at a 1.6% chance of DM last check, even sitting & clicking mine non stop, it takes about four hours to get a stack, and trust me, I've done it many times!!).
I have THREE 250 miners... myself and two rogue alts. I levelled to 250 on Kero first, just to find out, much to my dismay, I could never mine deepmetal solo. So... here comes the rogue.
If you make the ore more challenging to get, yet mined more readily, it's going to screw up the economy.
A. Everyone & their brother is going to start mining, when they don't even bother to smith it, which is going to drive the price of ore down, and people are going to look for prices to drop even further than they are already on DM, which is flat out not gonna happen, due to the other component costs involved. When I started mining DM on my rogue, I couldn't even smith it yet, I sold it to get money to level in smithing. Back then, 2k a stack was the going rate (and we're only talking last fall), I'd sell to a couple folks at a discount price of 1.5k a stack that I knew would buy at any time. The market is flooded with miner bot alts trying to make money to the point I've seen ore for 1k-1.2k a stack. I've dropped my DM to an all time server low, due to the fact I *do* semi AFK mine on two rogues on my days off & have things to do, so I rarely if ever buy ore. Want to see 1k deepmetal, and trivialize the thousands spent getting to 250? Well, I ain't playing that game. I'll tailor first, since I have a 250 in that as well.
B. Everyone is going to try to be a smith, much like everyone wants to be a tailor when they see how much they can farm their own stuff & make money. So market will be flooded, just like it is right now with lack of SS/Imphide sales. My DM sales already <insert nasty word> on listsold, the only way I sell stuff is if I do combo deals with augs.
C. It ain't broke for what it's intended for. Don't fix it for smiths. Mining is good for one thing right now... for smiths. And I've said since I was level 20ish when I started smithing, if you don't bother to mine your own at least sometimes, you're not going to make money smithing.
D. Want to do something interesting with mining? There's been TONS of proposals, including mining gold, silver, plat, gems, etc., so jewelers can use things, and add something else to the skill besides just smithing. I can mine silver ore, why can't I make it into ingots usable in jewelry?
Mining is easier than farming materials (yourself) for tailoring, not than buying them from others. That was the point I was trying to make... Miners can't "get exp yourself while" mining, nor will people mine while XPing. Making mining less AFKish, while not making it fully interactive and XPish will make it even harder for smiths to buy their materials from others, which is "easy" for tailors (etc.) to do now.
Mining is easier, but *way* more time consuming. I can easily go farm furs, silks, etc. (with the exception of the horrid kedgewater drop rate) and exp at the same time and I would make more money actually vendoring on the tailor, than I do now selling my smithed stuff. There *is* a reason that ExQ Type 2 augs sell for 225, and ExQ Type 5 augs sell for 400... it's the component cost. You're not going to find anyone now selling four ghost/warp ore for 50pp each... which is what ice kobold furs go for (four ore for aug, two furs for lining). Our component other costs on those augs is higher, but the augs themselves are lower, due to the fact... YOU CAN MINE IT!
There are many options to do with mining, that have nothing to do with making it a non semi AFK thing.
