Your shown rating is the rating the system is 99.7% sure you can at least play at
I'm sorry I don't understand what does that mean? Clearly I can't play at that level if I'm loosing >9/10 games? And what about the people who absolutely destroy us? Why is their rank so "low" then? But I suppose what you are saying is that the number is kind of meaningless? Then I would honestly just prefer if the number was hidden, this just makes it more infuriating.
Anyway, I think I'm going to try 3v3 since it seems to have lot more active queue, with some luck there might be more players closer to my rank. 2v2 seems to match me with just about anyone available. But then I would still need to spend several games loosing in 3v3 for the game figure out my rank and I'm not sure I have patience for another series of overwhelming losses.
Oh well.
