WoW: New NPC types revealed in screenshot
This screenshot shows a number of Ethereals with job titles not currently in World of Warcraft. What will these NPCs do for the player?
Level 85 queue times are quite lengthy. Blizzard developers know this and are implementing a remedy of sorts. In patch 4.1 a new Call to Arms feature will be used to rally under-represented roles/archetypes in the queue.
Will that incentive make you queue more as a tank or healer?

Community. It can make a decent game feel like a horrid piece of rotting meat left out in the sun. It can also make a subpar game an enjoyable journey with the right mix of personalities. Either way, community means a lot to the average MMO player whether they realize it or not. I find myself despising the act of logging in because those around me, friend or foe alike, enrage my very core.
