I don't like queueing as tank/healer in the expert and high level dungeons unless I go with 1-3 friends. The odds of running into someone either 1) terribly geared 2) clueless and just queueing as tank or healer for short queue times or 3) act like absolute jerkwards is pretty high. When I queue the other roulettes, I'll frequently queue as BLM (since the overflow right now is NIN which is a melee class) and just sit and craft or tab out and browse the web while I wait. Maybe if the reward for adventurer in need was better I'd queue more often as tank. If I want to make gil, I can sit and craft all day. Reward me with some tomes (even a small amount) or GC seals and we can talk. :3
