So here's the biggest improvement: Players can now Retcon as far back as they'd like regardless of level. There's been significant changes to the inner workings of the system, but for details on that we suggest you look for the official explanation.
Looking at the the cost of a full level 20 retcon, it still seems a little higher than it should be -- or is it? Unlike pretty much any other MMO, Champions Online doesn't restrict your ability selection based on a class. The problem Cryptic is facing is that if they allow for cheap 'n easy respecs, players may never want to roll a new character, which would kill the replay value of any MMO significantly coupled with the fact that you can also redesign your character as well. Retcon prices will probably still receive tweaks and changes, but when and to what extent is hard to say.
