Only problem(s) with Ecclesia were;
1) Level design. Once again there were really boring areas and repeating background graphics. Some of the areas were, in fact, inferior to Portrait of Ruin, such as the Clock Tower which wasn't too bad in Portrait (yes, go back and see for yourself if you don't believe me). In Ecclesia it was just meh.
2) Overworld map made the game feel disconnected. I wish the areas were connected like in Simon's Quest. That would possibly have made traveling/backtracking a bit more frustrating, but they could've put teleport spots here and there. Heck, some of the indoor areas could've even had SQ-esque Mansion entrances! I would've like that.
3) NO SILENCE OF DAYLIGHT IN THE VILLAGE. Lol, just kidding.. it's nothing to speak about. But it was a missed opportunity for awesomeness.
Other than that Ecclesia was really fun. I still prefer Dawn of Sorrow overall, but Ecclesia is better in other ways, challenge for example. And characters.
