I did like four, but I will agree with the bosses being annoying. For some reason they have a health bar, but it never goes down. You'll just be hitting them and suddenly they die. Synthesis definitely seemed pointless. Overall I feel the game is pretty good and I enjoyed it. Considering how cheap it is now and the lack of great RPGs out I'd say it's worth a purchase. Gabriel Celeste is in it too as an optional boss btw.
Living life without doing what you want, now that's just a recipe for misery
