I have to say that Blizzard Diablo 3 really fucked up. Everything is aimed at reaching a high paragon level in the first moment. And then end up with the same build as anyone else playing the same class as yourself.
Path of Exile is much more varied and you can do much more things there.
I can only recommend to every Path of Exile, Free to Play :)!
Yea i kinda agree with you on some things, thats why i think Diablo should only be played for a little bit, if you wanne go hardcore then POE is better for the long run.
