If you haven't played this game, check it out (at least the story) - it's become one of my favorite rpgs.
Good changes. I definitely abused Lune's Thermal Transfer bug during early/mid game, so I'm sad to see it go. I probably wouldn't have enjoyed playing her as much without all the extra AP generation.
Yeah as long as the target had burn, you were getting the extra turn. Someone said it only worked if the whole party was up, which may be why it didn't work every time.
And agreed about the ending - I had to put the controller down and think things through because my heart was torn.
