Taking some guesses. Based on raw numbers it would be more likely for those classes to be Archer, Scout and Swordsman only as the first two trees have less classes and the later still has the weapon issue to handle.
A - Some kind of archer/scout, it has a slim shape, heels and seems to be using leather. It does resemble Centurion but assuming D figure is a swordsman than it would be unlikely. My personal guess is for an archer, perhaps crossbow oriented.
B - Reminds me of Archer special costume and could be something like that, a lot of fabric on the main body and leather on arms and legs. Could be some other type of companion based class.
C - Stands for Cowboy, tho it won’t sound fitting for a class name given the name weight (can’t be Outlaw tho). Likely to be like a wild west outlaw class but could be something completely different, asterisk/star spurs are an iconic feature of Cowboys but, if i’m not wrong, they were used to poke horses while riding them. Could be some sort of pistol mounted class.
D - Looks like a tanky boy by the figure weight and these plate like pauldrons, could be a new 2h sword class as these are lacking since doppel. However it could also be possible to be some sort of commando class which is more into archer and scout, personally i can see it as a CON heavy class in scout being some sort of mercenary.
@fabricio_polo
It could be the case but these silhouettes don’t feel matching for F/M versions (tho as it could be), also as all hairstyles are short it isn’t clear. It’s possible to be the case but i don’t think it is.
