First of all the content needs to be good. I’m pretty sure the dungeons will stay trash tier like they are in the first act and will maybe get better over time. PvP in hack and slays was always a joke and only got better in “moba combat” like games like Albion and most likely in Corepunk in the future.
Dungeon+… well if only a portal opens every now and then tehre is no “+” there are only a few more enemys in an already almost empty dungeon.
The events in the first zone get repetetive and boring ultra fast like there are 3 events per spawn and some event spawners share the same event list. I don’tk now how often I helped that ghost but I even left these event aside at some time.
IF said content is quality content and the replayability is high then everyone would grind happiely. Sadly it looks like all the stuff D4 offers isn’t that outstanding it makes you waste a second thought on it.
Then again the basic game loop is fun so maybe they get the optional stuff good too, who knows?
