Which Profession To Choose?

Well potion's will be a common thing that will be bought most of the time, yet armorsmithing seems pretty good when you achieve master armorsmith and making heroic armor.

thanks

As for a fast selling marketplace profession, I would say Handiwork. My friend makes a ton of accessories and they all get sold almost immediately for any price since not a lot of people choose that profession and you don't get accessories from normal mob/dungeon drops.

Enchanting for Taming scrolls. It sold quickly generally

I went enchanting and cooking for the paladin.

My alt might have the other trades.
