The idea of the class based mode is to draw newer players and give them a fun environment to build skills and eventually appreciate the other modes. It's not aimed at the current community but rather the larger percentage of players who quit the game early on. The problem with Afps in F2P format compared to other shooters is it's not a fun experience at the skill floor, it's hard to "hook" them as a result so a class based system may help that. Quake Champions is a poor comparison, it's idea was potentially great but it's execution/engine prevented it from being realized. I don't think it would be the nail in the coffin, more players is always better.
