I tried searching waypoint for this but nothing, and there is no specific search tool just for the forum that I can find.
Many of the challenges involve missions I am not up to yet on harder levels. If I do them for the XP, must I repeat them to formally & successfully complete each campaign level? Will it forfeit any special unlocks, video, etc. for completing legendary?
If there is any resource available that deals with this please advise.
