I love love love love love love builds and customization... but I get that itch scratched elsewhere. To be honest, I would not like to see it in this game. One of the selling points for me was not the simplicity (that does bug me a little), but rather what the simplicity offers- balance. It is MUCH easier for the devs to balance these simple little cookie cutter builds than a mass of customized builds that people like me would min/max to perfection (and then watch it get nerfed).
