Playes 15 hours of it (1 being in queue tho) between saturday afternoon and sunday night.
I played 1 and 2, forever.
The 3rd installment I dropped within 2-3 months.
Yes D4, looks much improved (watched alot of streams of it, and a few videos).
You can tell they took abit of inspiration from Path of exile.
And even though its not nearly as complex, the fact that they moved in that direction alone is a big stepup from D3.
(heck even the skill-tree, that allows for "builds", instead of just hot-swappable buttons like in D3).
Diablo needs build diversity, its kinda the lifeblood of these types of games (imo).
Its what I enjoy most about PoE as well.
The "theres no right way", go about makeing your own character however you want.
You need "room" to be able to do so in the game systems (something D3 lacked).
