The epicness of the game is so high right at the beginning that we'll probably loose an important part of such a game : the feeling our characters slowly become powerfull and that the story gains in intensity.
We have already skipped over Flesh, clay, stone, bronze, and iron golems into fighting an adamantine golem. at level 4. Might as well be throwing atropals at us. Even a flesh golem should be a nasty opponent at our level, but it kinda feels like we the players are supposed to feel like huge badasses even at level 1 with world-shaking events swirling all around us. There's no time to move through fighting flesh golems to clay golems to stone etc. The goblins in Act almost feel like an outlier in comparison to that.
