Quite often in my guild one of the first questions a new priestly member asks is " what professions are best for a priest". tailoring seams to be a given, you can make your own gear and make and sell bags to make some gold. The normal "second profession" mentioned is nearly always Enchanting....At face value a good choice as you can then enchant your own gear and sell enchanted scrolls and also disenchant those greens for mats..but is it the best choice ? I found enchanting a very slow, frustrating prof at the lower levels , always short of mats and hitting bottlenecks, and no one buying those enchanted velums on a flooded ah, So in a moment of madness I dropped enchanting and took up herb gathering..was able to speed lvl it up to the same as my dropped enchanting in a matter of hours, buddied up to a friend doing alchemy and started swapping cloth for herbs and selling on ah any he couldn't use..hey presto! frustration gone, tailoring boosted and gold coming in.. I kept this up till i was lvl 80 and then..dumped herb gathering and speed leveled enchanting...A few runs through low lvl dungeons and cheap greens on the ah made it quite easy to do..and as i had saved up greens from lvl 70 up i had a good start on higher lvl mats + drops from wrath dungeons soon made it a profitable new profession . So my suggestion would be tailoring and herbs, skinning or mining until you get up to lvl 70+ and then maybe switch out to enchanting if you wish ...you might even think about herbs and Alchemy..probably more profitable than with tailoring ?
