DPS class with the fewest buttons?

[UBERHAXED]

Warrior. By far.

1. Turn on deliverance.
2. Pop unchained.
3. Use fell cleave.
4. Wait for unchained to come off cooldown and repeat steps 3 and 4.

Am I missing something here? Not only can you not use unchained in deliverance, but it has no effect outside of defiance.
