I started poe fresh first time and thought i would just figure out a build on the go, right as i entered endgame i switched my build to an established one and i don't regret it at all. Same for a friend of mine (im ranger he's warrior) we're both doing fine progressing through maps, yea we die but that's part of it we also carry on. About 75/76 lvl now. If we see ourselves die a bunch of times in row we start running lower maps.
And yea the gear is rng, but you have to use the game economy in your favor. There's a large number of players farming AND selling, so instead of playing rng with your resources upgrading and hoping an exalt will give you the stats you need, use that currency to just buy the gear you want/need.
And as many have said, the game is in early access, literally half the classes are missing.
It's ok not to like the game, just should have put a disclaimer that the fame is not finished imo.
