Just started.. coming from PoE2

Hey GD people! Just started and I think I'm about 3 hours in, first impressions:

• The game is great! I like its charm in the worldbuilding and lore. Playing PoE2, I was just blasting through the hordes of enemies, not caring for any of the dialogue. But GD actually made me want to pay attention to what's happening.

• coming from PoE2, the game certainly is a lot easier. But that's not a downside though, sometimes I just want to play and chill, not fucking stay on edge like what PoE2 does to you.

• I just tried "socketing" components into my weapon, and found out that it grants me an additional skill. I got the lightning nova skill one. Is it just me or is it really OP? It's my most efficient pack clearing button right now, but, yes, may be too early to say stuff like this. But it's good to see these skills be viable in their own right, unlike on other ARPGs where you need to follow a certain build to attain max efficiency.

• what should I do with looted rares/magic items? Is there sort of a disenchant/salvage mechanic? I've just been selling them.

PS: sorry for poor formatting, I'm on mobile
