Back in the day, the player majority even leveled mages as alts in order to gather gold quickly. In addition to their monstrous ranged DPS, mages also have tons of useful utility. As a mage, you’ll be able to conjure food and water, place portals to the major cities, and even earn gold from doing so.

Additionally, Shamans were able to wear mail armor, so any piece with spell power on mail set piece was almost certainly yours.
