Yeah, the insistence on trading as a key part of the game (despite the garbage trading system) absolutely murders your loot, which is just a huge drag in a loot game.
Global trading means drop rates and gear quality have to be kept down across the entire playerbase, so stinginess is built in deeply on top of GGG's inherent worship of time-wasting and RNG.
BTW, PoE2 separates skill gems from gear and removes color gem slot restrictions, so that at least frees you of the way PoE1 needed a drop to be good and to get good links and to get the colors you needed on those links. On the other hand, the simplified gem system is missing some life and fun. You don't even level gems by using them anymore. You just burn a higher level gem drop to level a gem you already have.
Sure, but there's also plenty to explore, especially for people who haven't played PoE1 and have to learn how things work from scratch. Given you don't pay extra for EA and premium stuff like stash space you buy goes to both PoE1 and 2, you get quite a bit for your early access ticket.
But probably more important that early access characters and stuff aren't available out of early access, so you are explicitly playing temp characters. Fine if one treats their early/seasonal characters as temp characters anyway, but someone else might not want to play characters with no future after early access.
