Currently I think we can all agree that our currently mining teleport, the Falador Mine, isn't all that great. If you're wanting to mine adamant ore the best place to obtain it would be the wilderness, and that's not always a great idea. Of course you can get Adamant from the Fally mine, but it's not an efficient place to mine it.
I feel like if we had a better mining location a lot more players would enjoy mining and wouldn't be pushed into the wilderness so they can obtain some decent ore. I feel like it would also make players enjoy smithing a bit more as it'll be a little easier for them to obtain the supplies needed to smelt bars.
So my suggestion is that we could either replace the Falador mine with Jatizso or the Jatizso mine could just be added as a second mining location. This mine contains plenty of mithril/adamant rocks, something which Falador currently lacks in.
I had suggested this before, but it seems to be completely gone from the forums. /shrug
