This sounds exactly like my idea about keeping a personal rating and basing matches off it. If blizzard does this it will make arena fair and eliminate farming gold with arena. I dont think arena should be use to farm gold. Arena should be a part of the game that puts equal pvp on the table. Nothing pisses me off more than seeing high rated players farming noobs in arena. This rating change will put players who are similar in rating up against each other. If they can pull it off everyone can breathe a sigh of relief.
