We are performing an update to our backend logic that will change the way "impact" is dealt. Impact is the "liberation" that players deal to enemy planets or defend events. It used to be that Helldivers needed to complete an operation (usually 3 missions) in order for impact to be distributed.
Now, each mission will deal impact, and completing an operation will then deal bonus impact. This is primarily done to make sure that everyone performing missions can safely say that they have contributed to keeping the galaxy safe, without the need to have the operation complete.
Hopefully this will make the system easier to understand, and the casual diver who only has time for a mission a day can still effectively help the war effort.
No. It's that your players are already using roll20. At that point, they should be open to try a new VTT.
Like how they're open to try different RPGs.
