Is EVE, Minecraft, Albion Online a Sandbox? If yes, i had a lot of fun playing this solo.
I played for a long time WoW, DCUO, HDRO and other MMORPGs Solo. And i had Fun
I don't expect to have access to all content like groups etc, but at least some things should be possible solo.
But you are right, it is as it is. Many will perhaps also be satisfied with the changes. It's just a pity for many, because it has been a lot of fun so far, I think that's why the dissatisfaction is big, because something has been taken away from them. If they had just introduced new things that solo players could hardly access, the scream would have been much less, I think.
