Only the first one has additional shit, after that the new league mechanic has been great, it's quick and easy to use, you can preview the rewards so you can just fuck off if you don't like it, it gives bonus rewards like the vaal shit last league on top of its own guaranteed rewards(and you can get more rewards too, not just the listed stuff) and so far the mobs haven't been too rippy at low level unlike the usual PoE1 league mech where they spawn 6 rares at lvl 2.
Also liking some of the campaign improvements, it is quite nice to know where you're going even if there's still some fiddling around to find exactly where the stuff is.
I'm lvl 16 and haven't found any move speed boots though so not going super fast, and stopped for a bit to eat.
