D3 and PoE are both great games that cater to different audiences. I put 1000+ hours into D3 for sure, and still think it's a great game, if you just want to log on and kill some shit for an hour and play something really generic and not thinking. That doesnt make it bad, just a more simplistic and basic gameplay complex. PoE is a great game if you want to log on and be really careful about shit and think a lot harder about 1000 intertwining ARPG systems. I dunno, both good games, serving different styles of play.
With that said though, even though I do like D3, I'm not coming back till they release something new, especially with Incursion league in PoE. That shit is wayyyyyyyyyyyy too much fun.
