Because if I win, I want to play a higher rated player. I don't care if when I win I get paired with a 26+ player. But why would I want to play higher rated players when I am losing?
When you're losing, your rating drops, so the restrictions on rating range will keep you from playing much higher players. If you're on tilt, you'll drop down enough to get to a point where you're more likely to start winning some games again.
The same is true when you're winning, your range will include some higher rated players. If you have steaks of wins, you get to where most players will likely be above the rating you started the session with.
1) "It's random with those seeking games the same time"
Yes, I know that. I am saying it shouldn't be that way. You keep typing it as if I don't already know. Saying it 1,000 times doesn't make it right
The system in place gives players some say in how they are paired by limiting the range of ratings. Adding even more logic on top of that, to massage the pairings, will create fewer potential matches and likely increase paring waits while the system tries to find some perfect fit.
Add to that, one person's idea of a perfect fit won't end up matching another's.
