Games I can grind for thousands of hours???

Anything that has the MMO experience?

I'm really enjoying black Grimoire cursebreaker I also plan to play atylss as well Erenshore I'm waiting for it proper release

Mostly looking for the games I don't need to rely on other players Warframe was good for this as well

Runescape is fun but the UI is not new player friendly I don't know what I'm ever supposed to be doing.

But I love the Runescape style combat though and grinding
