My problems with divinity original sin 2

So i bought Divinity 2 a couple of months ago, because of bg 3. I REALLY enjoyed it but there were some really big issues that made me drop it. The first one is that i think the game isn't really beginner friendly, yea it gives you some tips but i found myself searching for information about everything. But i could get over that as i got used to it. The second and main issue is act 2. It just feels random, like i can be in a area where the enemies are a little tough but beatable, but then go a little to the right and suddenly find myself in a scenario where the enemies are 5 levels above me. Like I did all i was able to in driftwood but i was still to weak of a level to do most of the encounters around the map. I don't know where the game want me to go. The only thing i know is that i should go to the masters of the source, but I was holding that off because i thought it's the last thing you should do. So i got stuck and dropped it. But i want to try it again so im asking for some tips on what to do or if its just a skill issue.
