I understand wanting to do all of the story together with people you like, and how the solo duties interrupt that, but I think in this case they should stay as they are.

Why? Well, they perform the task of being a baseline thing that people have to overcome as individuals, like basic skill checks so that the players can demonstrate, again as individuals, that they CAN and do know how to play before grouped content.

This is important, even more so than before due to the level skip potions.

There's also the fact that scaling the fights for up to even just a light party might make them too hard or braindead easy on release, prompting more problems than we have now with them only solo. I'd rather they put group balancing dev time into dungeons, trials, raids, and other group content.
