I wanted to get into PoE, but seeing how endgame builds play really soured it for me. Playing through the story using a variety of skills and dodging the attacks in the chaotic boss fights was a lot of fun, then I learned that an optimal build spams one skill and kills bosses before they do anything, and if you're not clearing that fast, you won't be making any meaningful progress because drop rates are tuned around the assumption that you are.
