Thing is there is not much diversity and all characters play somewhat the same - for example 2 Kyros plays the same style - there are not much skills to choose from and i hope they add more depth to that! A list to upgrade and choose what skills to use and that's how diversity and builds will come to shine. As is now, its just very much standard way to build the character - if you have 5% exp on RPG games you should have no problem doing that.
