I am currently lvl 15, still mincing around Act1.
LOVE the game. I don't understand why people say it's hard, like dying to the first few bosses over and over. I've only died a couple of times, once to a hag red circle outside of the first town and then to Draven who took 2 attempts to kill.
Just got myself a couple of nice upgrades, including weapon and I'm smashing through mobs. Playing Warrior, 2h Mace with rolling slam as the main ability, with shockwave totem and infernal cry. Also 30 spirit on Herald of Ash, making mob packs go boom.
I'm not far from the end of act 1 and apparently the end of act boss is pretty hard but we'll see. The pace is great, love the slower pace. The game is a piece of art.
Graphically, the game is a masterpiece. It also runs great on my rig, some stutters in new areas but I think that'll be shader compilation.
Will play a lot more over the weekend, can't wait.
