Q: About WvW Guild Missions Multi Server
You shouldn’t need to be on the same server generally for g-mish. However, some of the missions have a requirement that at least 3 members be actively repping and participate in the same event. It might be that you need at least one group of 3 on each world to trigger the threshold for participation.

Yes wvw and spvp need 3 people on the same server that do the objective in full.
So no people cant for example escort 1 doly out of 3 and get rewards on other servers.
