So if we sum things up with the most reasonable guesses:
STONE = Rock
STAR= Potentially Algol
SNOW= Setsuka
REPTILE= Lizardman
YELLOW= Dampierre maybe?
As for YELL, why can I only think of Yun-Seong? XD
Yellow certainly seems to work better for Dampierre than most other possibilities, but, although technically originally introduced in SC:BD, he's really more of a figure connected with SCV--and so at least a half-step farther into the chronology than I think they want to go with this game, from all indications. Besides, he's just straight one of the most absolutely least popular characters in the history of the franchise, who was divisive even among the development staff who produced him. I just can't fathom they would select him for inclusion before Hilde, Li Long, Hwang, and potentially Yun-seong or a guest character--it doesn't seem to fit their design priorities for this game and it would leave fans mostly scratching their heads as to the choice. But all joking aside, I think you could be right about Yun-Seong, and I think it continues to be probable that one (but not both) of the dao wielders would be included in season two.
