I don't understand the point here.. The players that have a decent shot of getting 12 wins, which is who this seems geared for, don't need the rewards that much. The golden legendaries, maybe, but most of the rest aren't all that important to people like amaz, reynad, etc..
Even those players have a fair shot of losing 3 games in any given 10 games. The high risk/high reward they think the competitive players want is more about recognition. High end arena players want a leaderboard. High end constructed players want exposure for their streams, money from tournaments, etc.. I highly doubt most of those players need gold/dust all that much. I see them sitting on 10k+ gold on their main accounts quite regularly.
