WOW PowerLeveling: With friends, you can split it afterwards, so no big deal
Patience, this is not class for someone, who wants to enter huge pack of mobs, kill them all in 10 seconds, drink a potion and move further. This is not class for people, who like to solo everything. It is not for people who want to get rich WOW PowerLeveling quick.
You will party almost all the time, thus amount of loot you get will be lower - make sure that, if you party with stranger, items are set on "orderly", otherwise you will get nothing. With friends, you can split it afterwards, so no big deal.
Most of time is spent on watching party members HP bars and their buffs. In smaller parties, it might seem like easy job, just buff 1-2 people and sit to regain mana, healing occasionally.
Cleric has 11, with 5 AOE (3 of which last *very* short). Clerics (not *muse*, but 2nd job already) are in high demand, but don't try to party with 6 ppl, you will only tire yourself and rewards will not be comparable to effort. Part 2:
1) Gather 15 Honeybee Needles from Needle Honey Bees. (Be careful! They can be aggressive!)
2) Return to Crow
3) Talk to Warren and earn your Job as a Dealer
