as i have played and boxed beta, artifact quest line and opening of the class halls (changes on spec and class) are yes solo, but saying that some parts can be done as a group. (so i would say do every party as a group and change window) some are only solo. its goes down to how the stuff is done there is some solo stuff normally going to a old dungeon or zone is solo. most of the time I find was going to place xyz then doing the small mini solo boss. change window kill boss again.


i would not worry about it unless your running silly numbers of toons.

everything i did in beta apart form the stuff we get next week (that once u done it u can skip it) could be done as a group.
