I'm disapointed

I'm a casual player I liked a lot poe 1 and was hyped on poe 2, few days ago I had some free time and started playing poe 2 and.. well i expected something different. Act 1 and I'm unable to take even 50% of a boss and sometimes even small groups of monsters kill me or leave me on 10% hp. There should be something like super easy league for ppl who don't want to study how each boss works and waste hours on it
