Sorry, bad phrase (bug/side effect). What I mean is that in ELO type systems, one of the unintended effects can be that higher ranked players can become protective of the rank/points they have been allocated, and may be adverse to entering contests in which there is a likelihood of having lower ranked competitors. Because of how points are pooled and allocated based on final rank/position. One way around this is to award points for participation, to entice the higher ranked players to play/not drop out/etc.
Unfortunately, GTS does not have AFAIK a system for rewarding participation in the form of points/ranks - you do a qualifying time, enter a race, and the matchmaking does its thing based primarily on SR. Any number of posts here complaining about that, as what you don't want is to be the only S/S or A/S in a lobby, even moreso if most of the other players are D. It is boring as hell, and the risks for something going wrong higher than the rewards.
Same if you find yourself in a lobby with higher ranked players, with what happens with D/S ranks. Can be boring as hell, however, the potential rewards far outweigh the risks!
See, what gets my goat is when we focus on the gameplay aspects, and try to pretend that the rankings/points don't matter. They do, because that is how each racing interaction is set up. I don't mean we should focus on the ranks/points as if they tell us much about the individual players, but rather when there appears to be a problem with how the ranks/points are setting up unsatisfying contests.
Er, not sure if that is expressing what I want sorry, need more coffee. I'm trying to make a subtle distinction between a focus on ranks/points for their own sake, and a focus on ranks/points when they seem to constrain the kinds of contests most players would like to have. How does that sound?
EDIT Just a thought that might be relevant. You know when you enter a lobby, and then when you get to the pre-race practice, and you see so-and-so has left the race? It probably is not a lag-quit. It may well be a player seeing the grid order in the first part of the matchmaking, then quitting then. No penalty will accrue. I am not sure if the game includes their DR points in the pool however. If it does, great! If it does not, means less DR points in the kitty for those actually competing.
