Consider me part of the PoE-fans!
Honestly, I think the main problem when comparing TL2/D3 to D2 is that the new ones simply chose different areas to focus on. I have both and enjoy both, for different reasons. But if you want top-notch, practically unbottable (afaik) ARPG with farming and amazing character upgrading, Path of Exile is your new soulmate.
And the graphics give a pretty damn great D2-vibe, something both D3 and TL2 failed at ^^
