My dungeoneering level is 47. I prefer to do the dungeons solo so I was wondering what is the best way to go about doing the levels now that mediums are available. Also, I really don't know much about the best ways to do this skill, like the best way to build up prestige and such. Should I stay on complexity 6 the whole time? If not when should I switch? When should I do smalls and when should I do mediums? Thanks for the help.
