What if end of season rewards were given out based on the highest ranked achieved in every playlist rather than the highest rank received in any single playlist? Would this help prevent smurfing?

For example to get the Gold reward you would have to get gold in Solo, Doubles, Solo Standard, and Standard.

Solo duel and solo standard are individual playlists, so you really can't get boosted or carried to a certain rank. And getting a Gold or Platinum or Diamond reward would have a lot more meaning if you had to earn that rank in every playlist...not just standard.

I would be much more proud of my end of season reward this way, and also have a lot more respect for those who earned the higher level rewards.
