In Legion Missions you have the option to extend or reduce LM using GP.

What if you could take the number of ships that signed up and fully completed a task and could reduce a LM by that many completions.

Example in a legion of 60 ...45 signed up but only have 27 Full completions you could reduce the LM by up to 27 hours using the political favor method.

Some of the LM are long when you can complete the tasks in almost no time. This would encourage people to complete the tasks they sign up for while having a use for political favor and more LM could be completed and could even add it in on successful missions every person that successfully completed their task along with the relics gets a chance to gain political favor so you have a semi regular currency of it.
