technically you could farm cows, pits, lower kurast super chests, ancient tunnels, mausoleum, keys for ubers, arcane sanc to kill ghosts for higher rune drops, travincal… I wouldn’t say you were farming a ‘handful of bosses’, the difference to me is when you do greater rifts you are 0-100% linear to boss, in d2 you farm areas with intent --> I intend to look for a stone of jordan --> farm nightmare andy, you want facets & gold --> make find item barb --> farm trav, want a shako? --> farm hell andy & meph…
So yeah, d2’s end game is more versatile then just rifts/grifts/paragon farming, heck they even streamlined the hellfire amulet by making it all have sockets right? I doubt anyone consistently spends 20+ hours farming those now…
Don’t get me wrong I still have the occasional seasonal fun in d3 but its less about farming endgame and more about unlocking a builds potential. Farming end game in d3 sucks, my hands literally hurt from picking up deaths breaths after a week of playing… or worse, having to make a zdps just because my character doesn’t fit the meta and I can’t get any groups for exp. Atleast in d2 I can pretty much entirely play solo when killing and join trade when I need something, d3 did some things great but it feels REALLY disconnected and breaks immersion. You can’t trade, mercs are solo , gem leveling is linear, paragons linear, the whole game experience is a linear progression is basically chasing an asymptote, you’ll never get that 100% perfect gear and if you are chasing the same piece of gear with .00001% better stats just to be ‘complete’ then i’m sorry --> my time is worth more and so should yours.
EDIT: Forgot to say this, while d3 progression is linear --> all fine and dandy you do you, d2 was more enjoyable because you are farming rare things so you can EXPERIENCE the game in a different way, like enigma, or beast, so you could use these items and play the game in a different way, seeing how OP this skill could get when you have +28 to all skills… Vastly different reward mechanism’s at play here.
