Sure, why not. They should do it across the board. It would make things more fun for everyone, because it is boring killing the field in a random room and I'm sure it is boring to get your doors blown of by someone. It would probably nix out a lot of 1st turn horse crap, too. At least at some levels to an extent. When you get a mixed room, over half the time, there is a decent collision at T1. Based on our online results, our ranking goes up...which would work great, because if you are beating nearly everyone in x pool, you should be moved up to compete with better drivers, as you have improved. At the same time, it wouldn't be brutal or unfair, because it is not as if people would be penalized like in some sims or demoted. I think that would benefit everyone. Very good idea.
I don't see anyone complaining that they can't race with people that will dance around them. Some people may get mad about not being able to race with faster drivers, in regards to it pushing them out of their comfort zones and into being a better driver.
Maybe if we could have rooms where we could select to filter out players below x rank, which obviously could be no lower than the original host's ranking. That way it could be toggled and you could race with your buddies, no matter who is better than the other and however far apart your rankings are.
The quick matches are kind of filled with dirty drivers, though. Tried it a few times and never clicked on it again. Either they forget they have a brake pedal or button...or they're pretty intent on running you into the weeds as soon as they see you're going to beat them. You'll have opened up a ten car gap and someone will just close that gap via braking by using the back of your car lol and sending you off into a sand trap. That's the end of the race for me at that point.
There should be a DQ system. That would be even better. It would be pretty easy and fair to DQ people by the game acknowledging that both cars are within a braking zone, but the car behind hit the car ahead with say...a 25-50mph speed differential between the two. Either your an idiot, had your head in the clouds or you're a jerk. All of which should DQ you for a race. They're short sprints anyways. If it turns people off to playing, it turns them off. Better to ruin one persons fun, because they're ruining many others'...than ruining many more peoples' fun by letting someone think that they can/should take people out/drive like an idiot.
It is just a game, but people also want to enjoy online play and that doesn't happen when people who don't belong anywhere other than dirty NASCAR rooms or national A events venture elsewhere. I don't like how they removed the kick player vote feature either.
Tl;Dr I think it is a good idea, just needs a lot of thought to make an overwhelming majority of people happy.
