The healers are same, just different angle (Lalafell's left arm and shoulder is white, for example)
The tanks are the same as well. The Warrior just has headgear turned off and the Roegadyn has a different angle with the breastplate, making it seemingly darker due to it's stance.

Based from the previous coils, very likely that casters will share the set as well and I wouldn't be surprised if monks shared a set with ninja's - Assuming they wear the same armor type in general.
