[pf] Dirty trick champ?

[SamsDisciple]

Perusing through the rage powers I ran into the rage power "savage dirty trick" and I was simply wondering if this puts barbarians in the lead when it comes to dirty trick maneuvers? For those ho dont know it the power allows you to once per opponent per rage deal an enhanced condition (both sickened and nauseated for example) as a melee strike and the enemy also takes your strength modifier in damage.
Another question dealing with this is how it interacts with greater dirty trick. The rage power states that the second status effect can be removed via a move action but greater dirty trick normally increases it to standard...

Yes, this ability is useful because if you combine it with Quick Dirty Trick you can make two Dirty Trick attempts every round while raging and full-attacking, imposing up to three conditions on them if they both land.

Brawler might have an advantage here though - they can use a brawling weapon (with the increased die from Close Weapon Mastery), plus their maneuver training, get all the dirty trick feats quickly, and use QDT during a flurry.
