I enjoyed the first playthrough but didnt find the game very exciting. The sphere grid is a nice form of customisation but you tend to just google a map to follow as a DIY attitude will leave you ill equipt when you find "that build" that you can no longer achieve.
Unless they have changed it to allow multiple resets.
I prefered D3 too. But got bored of that, i think the expansion came too late for me because id already ground(grinded)?? Myself out.
