This is the Hoth Rebel Calculator. It is used to calculate your TB from the start and see what is possible.
To start with, simply enter the phase and the average amount of waves you think your guild can clear on missions. Then select the platoons possible.
This will then work out from your guilds rosters, how many players can do each mission.
You will also be able to see which stars you will get just from doing missions alone. (They will appear as a star picture)
Next to that will be the total amount of GP to get the next stars. e.g 2 mil and 42 mil (that is 42 mil total for 3 stars. Not 44 mil)
From there you can use the deployment tools to work out how to split your guild deploys up to gain those stars.
