If a player finishes off the Mercenary tasks WHY should we have to redo them again for the Partisan? common SENSE would be it will automatically update that first part of the partisan when it sees we FINISHED the merc tasks already. Makes no sense to me why that wasn't obvious to include.
Doesn't it make more sense to get all the tasks you can in a zone/area and then start to do them? I generally look at all the partisan tasks in a new zone and figure out which ones I can do in combination. I focus on the partisan tasks and then figure I'll clean up the merc tasks as needed at the end.
