The reddit thread @Bateau linked above got me thinking about how the new-league grind could be improved, so I posted something about it over on the PoE forums. Basically some additional map crafting abilities to smooth out the Lab process, and allow creation of alts that get to skip the story section. I don’t hold out much hope of anything like this coming anytime soon, but it was a fun thought exercise to come up with it.
Guess that’s just a matter of personal taste. Myself, I’d miss some of the older ones if they were removed entirely. Having them pop up occasionally at higher levels is perfect as far as I’m concerned.
