If a newbie were to change the maximum level to, say, 15, they would be against people who recently "prestiged", which would be unfair. The min/ max level no longer is effective, so it should be "min/ max prestige"
Changing min/max level to min/max prestige will reduce the amount of control over what players join your match. I would prefer it if prestige was included when determining the actual rank of a player, and the maximum level limit was increased. So, for example, a player with a rank of 15 and a prestige of 1 will actually have a rank of 65.
Yes!! So, the thing should be changed to have ranks from 1 to 550 (50 * the 10 prestiges, plus the 50 levels they reach AFTER they have prestiged for the 10th time)
