The Heart of Thorns expansion is changing guild missions in Guild Wars 2. How so? That’s what today’s website update is designed to answer. New guild mission types for WvW and PvP will be added to the existing PvE types, as ArenaNet seeks to diversify the ways that guild halls may be leveled up.
There’s also a mission preference option that will allow guild leaders to select what sorts of activities they prefer. It’s worth noting, however, that abstaining from selecting a PvE, PvP, or WvW preference and instead opting to receive all three types will also net your guild a 10 percent favor bonus.
Today’s update also covers the new guild mission panel, instanced missions, personal rewards, and more.
