This being said, I do think solo content will only invite more solo content which imo would be a detriment to the game. So if their goal is only a coop game, then they should NOT add anything in that’s for solo even if it’s 4 man but easy enough to solo like the quest zone.
I already saw the plagues of “individual” play in there.
No one would run around together. Everyone did their own thing and ignored eachother. This is not how a multiplayer game should be. This is partly because quest progression being different, but then people would be popping in and out too.
So there’s definitely some issues with that quest zone that stems from it being able to be soloed and a design flaw which makes it optimal to continue playing it solo.
The more solo they add, the more solo will be requested to be expanded upon, until the solo players demand gear tracks to fully bis gear without ever touching multiplayer content, which imo, would be terrible for the game.
It’s definitely a slippery slope.
Also, adding more solo and PvE content would invite a lot more types of players to the game (money) which could be an overall plus for the game. Really depends on the devs design goals.
