Ddo was absolutely awesome and much better than bg3 from a complexity and rule viewpoint. But was always too hard to find people at your lvl to play quests. And the lack of enough solo quests made you simply stagnate without online friends.
DDO these days is 1000x easier to solo, you can easily do about 95% of the content with one player and maybe a hireling here and there. It is a bit dry though so to actually enjoy most of it a friend will help a lot.
