MER Checking in on Mining before the Nerf

As I wrote last month, I am going to try to look at more specific aspects of the monthly economic report going forward.  We got the March report last week, just a couple days after the April update introduced a series of nerfs to both ratting and mining.  I took a measure of ratting last month, so this time around I want to get the “before” picture for mining.

March 2019 – Mining Value by Region

There was, as usual, a lot of mining going on in March, a good chunk of it in Delve.

Delve is, of course, where the Imperium lives.  Second place goes to Esoteria.  Both regions were up over February.  Overall, according to the raw data that comes with the report there was about 56 trillion ISK worth of ore mined in February, which went up to just shy of 59 trillion ISK worth of ore mined in March.

The price of ore itself was up just a bit in March.

March 2019 – Economic Indices

I am not sure that is enough to account for the difference between the two months, but overall the count is close enough that the two months are pretty on par.  February being three days shorter than March could make up the difference.  Dividing the total amount by the days shows the per day yield tilted towards February, with 2 trillion ISK per day versus 1.9 trillion ISK per day in March.  Still, pretty close.

Last Tuesday the update hit with nerfs to Rorqual mining, specifically:

  • Reduced the bonus to shield boost amount provided by the Industrial Core to 60% for T1 Industrial Cores and 75% for T2 (was 120% and 140% respectively)
  • Reduced the base duration of the PANIC module to 4 minutes (was 5 minutes)
  • Increased the bonus to mining foreman burst strength provided by the Industrial Core to 30% for T1 Cores and 36% for T2 (was 25% and 30% respectively)
  • ‘Excavator’ Mining Drone base mining yield decreased to 80m3 (was 100m3)
  • ‘Excavator’ Ice Harvesting Drone base cycle time slowed to 310s (was 250s)
  • Excavator drone volume increased to 1100m3 (was 750m3) and Rorqual drone bay volume increased to 8800m3 (was 6000m3)

Reduced yield and slower cycle times for excavator drones are direct swipes at Rorqual mining efficiency.  Reduced PANIC duration makes Rorquals more likely to die while waiting for rescue to arrive and larger excavator drones means that Rorqual pilots won’t be able to stash so many excavators in mobile depots to save them from destruction.

The Rorqual also won’t provide as much protection to mining barges and exhumers in their fleets, though the mining yield for those craft will go up, an incentive to fly the smaller and more vulnerable subcap mining ships.

So the question is whether or not these changes will have any impact.  We will have to wait for the economic report for April to come out next month to see.

Meanwhile, going back to last month’s post, the top sinks and faucets chart shows bounties were down a bit, continuing the trend from February.

March 2019 – Top Sinks and Faucets over time

Overall February and March were not that far apart, being about 70 and 71 trillion ISK in bounties respectively, but the chart is trending down and the bounty payouts per day were almost 2.5 trillion ISK per day in February while that sank to 2.3 trillion ISK per day in March.  We will see if the April update changes, which hit fighter damage application against sub caps (which hurts carrier/super carried mining) and nerfs to the Vexor Navy Issue (the favored AFK anomaly sub cap) keeps that trend pointed down.
