Some complaints:
Mapping is not very fun. Even the last time I played PoE1, in 2016, mapping was much better. You had cool unique maps to find, you could play certain levels as much as you want as long as you had the maps, etc.
Mapping in PoE2...move a long a giant, infinite, overworld with no rhyme or reason and use tablets on towers, to incentivize you to stick around in that area a bit longer. So far, the tablets are nothing crazy, AND they are insanely rare. I'm sure this is just a stepping stone as it's definitely still early access. I'm positive they have a lot more in line for end game. Some things I've heard, but not experienced myself as I am not level 90+ (74). By the time you finally get points to put into each sub tree in the atlas, your build is basically godly, as to get points you have to kill the breachlord first to unlock the breach tree. Just seems kind of backwards, have to beat the hardest boss of each mechanic to unlock 1 point in a tree.
But yea I'm finding end game kind of boring.
