During the last free play time, I was able to sell my Elixir of Tongues stacks on the AH for close to full price.
I don't know if people have had similar experiences with Orboreal Shard, or Immortal Shard, but that could be reason enough to choose Elixir of Tongues as your gold sink of choice...
I tested in Tanaris, and I got dismounted (35/35). It might be specific to cata zones.
Side note, I just figured out I have been saying "Tanarsis" for the last 20 years.
EDIT: My mistake, I missed the reference to old school flying. I can mine while mounted if I remain in mid-air.
I had some characters with 5/5 dungeons complete ready for this weeks reset. However on logging in to those characters, the quests were removed from their quest log.
I'm not sure what F2P has access to compared to Vets, but check out https://www.wowhead.com/guide/professions/knowledge-points for a complete list of sources. Some of these I didn't even know about until right now!

You must be grouped with someone 10+ (or 11?) levels higher than you to enable legacy loot rules.
The other way is to be grouped with a someone who can trade it with you. (Int or Agi DPS class). Both of you need game time to trade, and it must not be an "upgrade" for the other character, or...
Further to this, now we can save a lot of gold, and spend it on things during the next free game time.
What are you saving for?
How are you going to get the gold to pay for it?
I am eyeing of a nice shiny Lightforged Warframe, just gotta save that gold.
