How people feel when playing the game MATTERS way more then MATH. What the healers are saying on my server is that "f Qing for the 50 game, I'm on my alt, I'm not going to queue anymore..."
Yes, the math might say that it all works out.. but the user experience for the healers is "ROFL, I'm re-roll someone who can get 4 tank medals in 2 clicks"
