Low amount of classification points when winning a ranked

When I play a ranked a Win, the amount of points that i won is too low in comparison with other people. I usually won less than 30 points.

For example:

PS: My bro has the same problem, account: Fingoldfin

This is something they acknowledged too late to fix for this season. However after some convincing the have become aware of it being a problem.

They are internally testing some matchmaking improvements as we speak, and are rolling them out slowly for different ranks.

Unfortunately your problem is unlikely to be fixed until next season, which is some 7 weeks away at least.
