Unless I missed it there seems to be no way of retracing one's progression in the rankings, neither to know exactly how many points you earned or lost in a game unless you recorded your previous rankings on the side.
A fairly easy improvement could be to list one's ranking below each completed ranked game in the game list. I think it would be nice and might encourage more players to remain active (don't we all want a thriving community of active players?).
Good idea I admit I haven't thought about that but now that you suggest it It would be Mindanao nice to see where my downfall was lol. Cya Around.
