They need to seriously fix these quests...its kinda BS you need co op to complete a quest properly. Withermoor and slane should just show up at those points if you need them but it shouldn't have any bearing on whether or not the quest is complete. Call to arms is also BS I recruited 2 seekers to help me fight and it never closed...So call them to arms and saving them doesn't reward us with proper help in the fight...stupid.
