It has an amazingly mind-boggling skill tree, with over 1300 nodes on it - That's insane!
There are absolutely loads of different character builds possible.
There is a robust end-game system via the map system (the opposite of playing the same areas over and over, really).
Etc, etc.
Which is not to say anyone is obliged to enjoy it, but is a person is a fan of the genre, this is about the best it gets, frankly.
I have over 40hrs in so I understand where you're coming from.
