I just beat the game as well, with a level 48 warrior. I, too, really enjoyed the game. I found the latter parts of the game to be a little less than desired.

I was really disappointed that the Council of Seven was killed. I'd known Mardaneus and Goemoe for the whole game. To see them casually killed was painful. Similarly, Bronthion and the dwarf were good characters, who didn't deserve such a trivial death. I'd rather they were imprisoned, or turned to stone, or something, so that I could rescue them later.
The ending itself needed some work. The demon's death scene was good, but I wanted more after that. Where was the triumphant return to Rivellon? What happens now that Janus is dead? Is the Source now repaired? I was curious about the statue, but I get it now. That's cute, but I'd rather see some more meat than a silly joke.
Are there different end game scenes for each of the three classes, or do all characters show up in full armor? (I realize that most characters are, in fact, wearing plate armor at that point...)
