Yea - I think I will.
I know D3 was a disappointment in many ways, but in my opinion, RoS ' release was a concession that the fans know best (admittedly, yes, they still failed to ever implement PVP but D4 should correct that), and the Devs tried their best to address the shortcomings of Vanilla.
I have high hopes that D4 will be a very worthwhile investment
