No rating system in existence - graded, tiered, MMR, Elo, whatever - has ever not had people stressing themselves out and arguing that they are unfairly trapped below their "true" rating. If anything, this system is probably more favorable to them because all but the most quasi-AFK 'hardstuck in bronze' types stand a moderate chance of eventually landing on a lucky streak into the next rank and earning some kind of ephemeral validation.
