I've completed 1000 villain fights on both Edwarda and Nike while no events active, meaning no mythic orbs in the drop pool.
1000 fights shows Edwarda having a higher chance of dropping equipment orbs compared to Nike (+2.7%)
Lets compare this to my previous snapshot at roughly 500 fights.
Here we can see that Edwardas orb chance is the same at 18%, while Nike has dropped 1.43% (from 16.73% to 15.30%)
We can also compare Edwardas villain fights against Edwardas mythic days drops.
Equipment orb drops are down 2.82% from 20.82% to 18%
Shard drops from mythic days Edwarda lines up against the increase in cash drops on villains (-6.63 shards against +6.37 cash)
It should be noted that 1000 fights is a low sample size and while we can get some indicators from this, drop variance is contributing to these numbers.
