Loving it so far, lots of build diversity and story is engaging and well acted out as well.
The world they have built though is the best thing, huge map but also every area feels unique and different to explore, it makes you want to look down every path and the enemies are nicely different in each area and offer different challenges each time. Boss design is really cool as well, I can imagine on high difficulties some of them will be a real beast to take down. Up their with Skyrim and Witcher 3 in terms of worlds you love going back to.
In Act V at the moment but nearly hit 50, looking forward to what endgame offers but feels like I have barely scratched the surface and there is loads to do.
