It occurred to me that a great way to expand game play would be to add more school specific quests.
I understand that the storyline has to move along and that those quests are pretty much universal. But that can get a little boring when running your second or third or fourth character.
Why not add some more quests that are geared to the character's main school of magic? That way you can explore all the different schools and get some completely different experiences (and perhaps some special treasure drops) in the process. Those quests could continue all the way through the highest levels. That would certainly add a lot of play value to the process.
PS, I would really, really love a Minotaur pet. That would be an excellent, high level, Myth School quest reward. Don't you think?
