The great flood – CCP makes massive changes to drop rates.
This is a case of Icelandic logic gone wrong, very wrong.
Back in March of this year, CCP announced that it would be tinkering with the loot tables, i.e. drop rates in missions. The purpose of this tinkering was to reduce the number of minerals that mission runners were getting from their loot. The logic behind this was, minerals should come from mining… primarily. Secondly, it should come from the refinables dropped by drones in missions and the 0.0 drone regions and finally, minerals should come from missions.
