Queue into DF as healer = get tanks that pull single packs and take mini breaks inbetween each pull. Or you get the tanks that try to go fast but end up dying because they don't know how to look at group composition and pull appropriately (no, you should not pull the entire zone when your DPS composition is BRD and MNK or if your BLM has an average ilvl of 70).
Queue into DF as tank = get healers that never bother to weave in and out of Cleric stance to add damage / Stoneskin @ 20% HP of last mob for continuous pulls
You really just can't win no matter what when you queue solo DF.
