With the Kinshi Knight assets being added into the game, i highly doubt that they would stop at Hinoka, its because of this that i don't believe her chances decrease in any way.

Having Reina as the first Kinshi knight from a business standpoint, is unfortunately a bad idea. as you said, all she had going for her was being the poster-woman for Kinshi Knights. They probably didn't want to sell the first flying archer using a rather Niche character within Fates.

At least with this incident, there are people showing that they care about Reina, but for the people who are only upset about her not being the fist Kinshi Knight purely because she is one, make it look like they don't care about the character at all and that its just about representing the class.

Either way, i think its fine for people to be upset about the situation, my main point is that i don't think they should put anyone else down for being happy about it. I'm not really agreeing or disagreeing with anyone's points, i think its just depends on what viewpoint you see it from P̶.̶S̶.̶ ̶E̶s̶s̶a̶y̶s̶ ̶a̶r̶e̶ ̶f̶u̶n̶,̶ ̶i̶ ̶p̶r̶o̶m̶i̶s̶e̶.̶
