Like in September, I processed the downloaded Dotlan data for October 2015. Let's see the ratting charts first:
You can see that Bloody Omir did a great job. Highsec ratting increased a lot, nullsec got a new record. Lowsec didn't simply got a new record, but beaten the old one by 20%! I'm pretty sure that such "holiday events" (WoW term) will be very common. I wonder who will come in Christmas. Maybe SoE will ask for our help to bring presents to poor kids in planets breaking blockades of Grinchy pirates?
Deklein lost 3M rats. To see how, I sorted the systems by difference in rat kills in September (corrected by 31/30) and October to see if there is some pattern:
Seems someone moved to this zone and hit ratters hard. Checking the killboard of these systems shown awful lot of presence from a certain alliance, but the diplomatic update of the Evil called them irrelevant 8 times, so they can't be the reason. Probably Bloody Omir caused that 1T worth of loss of income to Goons.
It's hard to not see that all Imperium alliances lost rats in October (except - you guessed it - SMA). Russians and renters increased their performance. It worth noting that XWX increased rats, lost land and still underusing its land horribly, so I expect further growth and consolidation. Other winners were Esoteria dwellers and ALTS.
The whole Imperium lost ratting, providing the worst performance in the last half year. The numbers don't match with the older posts because I added Void.. to the Imperium retroactively.
