I've always been concerned about the time sink I see that is needed to succeed in PoE. Is that also needed for the sequel?

I saw the skill tree for PoE 1 and shit myself

Plus the whole F2P and "the auction house is the end game" that I hear has me a little leery

I just want to play a dungeon crawler game and not interact with anything else period. No social, no multiplayer, no dailies nothing. I loathe free to play actually quite a lot because it's manipulative as hell and tries to get you in is daily ecosystem

Can I still enjoy PoE 2 even being an absolutely filthy casual?
