Thanks to whoever tagged me.
I need more information before I focus on what is being said.
Are we talking about the KotS missions?
If so, KotS is a PvP competition and the rewards from completing the KotS collection are pretty good. This is why the focus of the one set of missions was around PvP. Which only one collection set would be missing if you are PvE only. Though we have tried to add PvE to as many missions as we can, it won't be an option for all our missions as some of the rewards are going to warrant a bit more work.
That being said, some of our missions are going to be focused on one game mode, like the Asymmetric missions that drop you the gift containers. Often these missions are to drive participation.
