My husband and I have been trying to capture resources and keeps.
Problem some times even though we fought our way in and help secure the Keeps we do not get the reward of the mission.
Same thing in capturing resources quest, if we do not get there in time before the banner is full it will not register that we completed the quest.
Idea; if your faction is in control of a Keep or resources and you have the quest for it you should get the achievements to register that you completed the quest by going to the object and stand there a few minutes.
It is frustrating to complete the quest when you go to your objective only to miss out due being late and someone captures it just as you arrive.
We tend to make sure we support our faction and contribute by first completely securing an area , I.E. fix doors, walls, make sure no enemy is hidden, by this time and we miss out on completing our quest due to not standing in the right spot or close enough to the banners to get the objectives.
Developers please make it where even if you're faction capture a Keep or resources if you are on a quest you can still get the objectives by standing next to banner for a few minutes and complete the quests.
Thank you for your time and consideration.
