To me it still looks like quite fast a player arrives at the point of Masterworking towards perfection and doing 10min pushes vs hardest AI mobs possible.
I never liked the idea of "endgame" being who can 10-15 min run the hardest rng content possible.
I prefer lvl 90-100 being a ~4 week journey withh small rewards in character power, more of a personal achievement.
Alongside that I like a wide range of places where I can go treasure hunt for stuff I can use/roll a new char with/trade away and buy something GG, a couple of ~10-15 min xp routes that are OK alone but give more in group and then ofc a few hard bosses that drop unique stuff that I can trade away if I do lots of bosses or buy if I dont like doing bosses.
Then eventually I will be lvl 100 with a GG char and most likely quit or do pvp if there is a scene for it.
D4 still has none of this, only a really fast journey to 100 then min/maxing alrdy rolled stats to perfection while pushing as far as I can vs the AI.
