End of season rewards

I noticed that your rank shown on your profile is no longer your highest rank achieved in the season but what it currently is , while I can see why as they added decay I was wondering if it had any impact on end of season rewards. Are the rewards given at the end of season still dependent on the highest rank you achieved during the season?

It was changed to a seasonal quest, requirement of 50 wins in ranked mode to be eligible for rewards. Unknown yet if top of the ladder will get an additional reward (which was an extra armored mount variant),

The rewards by themselves are unchanged. They’ve only changed the requirements needed to be met in order to be elegible.
