Posting from class, so I'm lacking in time to formulate a massive report. Here's a couple o' comments:
I played a 1st-level Mystic with fairly well-rounded stats - Con and Cha were lower than the others, but everything's 12+. Didn't have to blow any Hero Points, but that's due to 2 things - 1)luck and 2) Mage Armor. AC 17's pretty solid when fighting the equivalent of gobbos, orcs, and a 2nd level Warrior. Maximize Spell rocks mightily under the PP-based casting system. Also extra-useful: called shots using True Strike. Other sick stuff of note: 1st level Supernatural Playboy had AC29. 1st level Avatar Champion had +9 to hit, +7 to damage, connected almost every time, mostly due to mad bonuses. More thoughts later, maybe.
