The purpose of a handicap system is to make the game more enjoyable by enabling players of differing abilities to compete on an equitable basis. The system would provide fair handicaps for players regardless of ability, and adjusts a player's handicap up or down as the player’s game changes.
Its a ladder for a reason... Automatch is played competitively, atleast that's the reason games have a ladder. If you want to just have fun and enjoyable game then find someone and play custom games with them.
