Well it’s a diablo game made by modern blizzard…
So about 1 week of content
And 1 week of repeating that content to find better gear and beating any bosses/pits/nmds you wanted.
Then getting bored and quitting until the next season, same as always.
There’s really nothing in the gameplay loop beyond that unless you really just enjoy mindlessly farming gear in order to mindlessly farm the same gear slightly more efficiently.
If the pvp wasn’t a joke, I’d feel more inclined to really perfect a character, but the game has to be designed from the start with pvp in mind, and D4 just wasn’t. The new “raid” thing might get a bit more eagerness to stay on the gear treadmill a bit longer, but again, it’s not really an endgame since it’s still the same exact gear, and frankly group content has been incredibly easy in all other facets (ROTA uber bosses are basically loot pinatas).
That all said, still looking forward to the game for what it is, a nice ~2 week diversion every couple of months, and something to tide me over for a month until POE2
