Ranked 1v1 Max Honor Points reached?

Just started playing ranked 1v1 since new season started. Forget about all other ranked modes, wait time in NA is insane. Wanted over 2hr yesterday and nothing...I only play 1v1 now.

In ranked page, it says I have 2500 honor point available to get for this season. However when I get medals for 1v1, instead of getting 20-40 honor points, it says 'Max Honor Points Reached. MP given instead'. Why is that? Is there no other way to get Honor Points besides joining and winning matches?
