Like in November, I processed the downloaded Dotlan data for December 2015. Let's see the ratting charts first:
The Frostline content once again boosted ratting numbers in all zones. We can expect such content to arrive bi-monthly.
There isn't much interesting here, except for the collapse of Querious ratting due to the arrival of Pandemic Horde.
Now there is something to see here: Goons, FCON and TNT lost lots of rats, while various Russian entities and renters increased their performance.
The Emporium (formerly CFC) ratting dropped a lot, only a few months seen worse data and those were a year ago. It's hard to not link this to the very high home losses and the departure of ratter/ganker corp BAT. It's early to say "the collapse has begun", but it's definitely a good sign.
