I am forecasting out toward the new expansion to prepare for what will be profitable.

Are potions still viable? From what sells and what does not, I am about to sell potions seat on the Ironforge Exchange to another item.

EDIT: Perhaps I should rephrase that question as to "What type of potions are most necessary for Dungeon groups and Raids?"

I still don't like potions...futures are definitely lower.

Potions have not been a good item for profits for me. Healing and mana potions will sell but just not worth it.
Elixirs on the other hand sell well and at a decent profit. Haven't looked into the expansion at all so no comment on that.

If you have the means, roll a druid and make him a miner/herbalist. I highly recommend it. They are so choice.

I am highly suspicious of all druids...I think that they changed the spelling of their name.
