Federation Rank Grind February 2021? I'm reasonably new to Elite Dangerous and have been grinding Federation Rank for a while, up to Lieutenant Commander, at Ceos/Sothis, however have started to notice the number of missions declining.

I understand that the fastest option is evacuation missions from burning stations, however there doesn't look to be any at the moment. 

My question is; is Ceos/Sothis the best option or should I start looking at Canopus/Exphiay or even Sol as it has so many Federation factions?
