Awesome! So I think that this is what we know now:
Warriors
Korbin – Legionnaire, dwarf male, sword and shield
Unknown Name – Katari, qunari male, two handed
Unknown Name – Reaver, human female, two handed
Unknown Name – Templar, human female, sword and shield
Rogues
Hall – Archer, (human? elf?) male, ranged
Unknown Name – Alchemist, dwarf female, dual wield
Unknown Name – Assassin, (human? elf?) (female?), dual wield
Unknown Name – Unknown Class, (unknown race and gender), ranged?
Mages
Unknown Name – Arcane Warrior, (unknown race) male
Unknown Name – Elementalist, human male
Unknown Name – Keeper, elf female, support
Unknown Name – Necromancer, human female
If this is the case, then we know the race and gender of most of the characters. For the males, we have 1 dwarf (Legionnaire), 1 qunari (Katari), 1 human (Elementalist), and 3 unknown races (Archer, Arcane Warrior, and Unrevealed Rogue). For the females, we have 3 humans (Reaver, Templar, and Necromancer), 1 dwarf (Alchemist), 1 elf (Keeper), and 1 unknown race (Assassin).
Looks like every race/gender combination is represented except for female qunari. The picture of the Assassin doesn’t look like a qunari. I find it hard to believe that there’s not a female qunari, so something must be incorrect about what I have above. Possibly, the Assassin is a male and the unknown (likely ranged) rogue could be a female qunari? It will be interesting to see how this shakes out.
