Every set so far we get to see with the previews. More proof that catering to classical armor weights is not the norm... We get this:
A classical representation of tanks in armor and mages with dresses... The middle term gets a bit hazy, but it still might qualify as "medium" armor.
but also this
If we had this same screenshot but without weapons, I bet the only ones I would be able to tell would be caster/healer but just because of the dress-like silhouette. Also noting that Maiming this time around shares a set with Scouting... interesting.
Again, apart from the healer and caster, all the rest looks quite undistinguishable
Fell Court of Troia SS, which likely has people wearing the dungeon set and the only one that conforms to its role is the tank. The Samurai on the back looks like scouting or aiming. The lalafell Bard looks like caster with a ninja-esque headpiece. I'll personally bet that Healer will share this Aiming model, and what the Samurai is wearing will be also for Scouting and Casting. With some minor variations, of course.
