So are you guys going to retroactively give the people the Rep they earned through leveling before you implemented the 250 Rep per level?
There are no plans to do this. At the time folks earned these earlier levels, Rogues were significantly cheaper to purchase and Reputation was earned quicker based on how things were calculated at the time.
Based on a lot of data and some feedback, we feel these adjustments are good for new players (who earn a Rogue pretty quickly) and add enough challenge to existing players.
