its pretty hard to lvl up but if you do instances often like i do or quests that give you tons of items (that are of no use to you) to disenchant, the sure go for it. you could always make a low level Enchanter character, mail him all the BOE things you greeded in the group, and let him DE the stuff and enchant more. I do the same thing with tailoring. my mage is lvl 25 and hes making things that are 34+. anyways once you get high enough enchanting you can start running low level instances like SM to farm small radiant shards. very effective. at 70, get an instance that drops small radiant shards almost off all its blue BOP`s, that means 4-7 per run (since essence of fire is only like 1g on the AH), for fiery you need 4 small radiant shard and one essence. think about it...20g after 15-20 min (if youre an AoE class, mage, pally, lock.... you`ve got an advantage in farming, round them all up and DoT). by the end of2 2 painful hours of farming one instance, you can enchant people fierys for 20g.

phew that was huge.
