Speedrun speed runs?

Balance and consistency with minimal down time out of fights, constantly chain pulling from one set to the next for fast consistent take downs?

i'll take DRK-SCH-BLM-SMN all day any day.

Eos can handle the boss fights and 75% of the trash, ill act as a pesudo second SMN and watch everything melt.

WHM maybe be better here and there under certain circumstances but i'd rather the security of no OOM chance classes.

[also lack of having to co-ordinate with the DRK about Holy vs BP timing, just DoT and go]
