I don't know what your point is here, are you saying that people should only ever make those two races in customs? That would imply that the only reason people ever race is for the sake of rs gains and that everyone would have to want to minmax, instead of just having fun playing the game.
Your first sentence references points, which makes me think racing points, which makes that sentence read like you want atock races, but you later say "we" (who tf is we??) don't want stock races so it can't be that. It's not like custom races award points either so I hope that's not what you meant either.
If you're just saying any non minmax races are pointless, then yes of course they are, but so is the entire game... because it's a game. Join whatever races you want to join and let everyone else join/run theirs, live and let live. Also never presume to speak for everyone when airing personal opinion.
