It is a role playing video game. How can story and characters come secondary to mechanics?
Because it is, first and foremost, a
game.
And before that the decision to make it was based on the desire to tell a story that involves characters. Reductive reasoning aside is there any other reason why you think mechanics should be the focus of a role playing video game based on a franchise infamous for being about the story and characters first and foremost? I can quote the PHB for you if you would like.
I would also like to include a plea. Everyone discussing on this forum does so of their own volition having read the rules(I would hope) and being sound of character and mind. We do not need policing. We are aware that it is EA and if you read out posts you will see that we usually include caveats when discussing points that may be changed by full release. We do not need you to remind us. We also have eyes and brains. Please do not dilute the conversation with a non factor in an attempt to play nanny.
