As long as a wow powerleveling guild has a leader it needs guild officers. The players should keep some of the administrative burdon off of the Guild Leader and provide players someplace else to look for help, when the Guild Leader is not around.

 

In a PvP guild, they would purpose to help arrange arena teams and battle ground groups. A guild officer's ideas really depend on the guild's ideas. In a wow powerleveling guild they may be there to help players by pointing out the best places to level or to help organize group questing. In raiding guilds, officers are likely to organize and run raids. In any type of guild there could also be a class officer, banker, raid leader, and many more. Even though they will never be an officer, they still need to know where they fit in. That's what ranks are for. The ranks that a guild need are really determined by the type of wow powerleveling guild.

 

The exact types and numbers of officers really depend on the guild itself. Officers should take a lot of responsibilities, and the membership at large looks at them as a reflection of the wow powerleveling guild, so choose carefully. All you need to wreck a guild is one officer flying off the handle at someone and the guild can fall apart. Once a guild is formed, many players need a purpose or place in a wow powerleveling guild.
