In the past there has always been questions of does luck work or not, what does it do, is it broken, etc. With this event the affect of luck is clear, a few hundred points different makes a huge change in drops. It's nice to see it really working in a clear way that's hard to debate.
Pretty much the only way to see luck at work clearly prior to this event was the Saltpeter/Niter Deposit size mechanic. The luck spreads seem to be identical in egg drops as the spread in Niter Deposit Sizes. 2200-2400 Luck seems to be where it gets fairly dependable, less than 1800 and you are pretty much just wasting thorns 2700+ and the eggs just flow in. Pretty much anyone with a smith/tailor/Imbuer and 600k clean up points can put together 2400-2600 luck suit at the cost of some runic kits and hammers and be in the luck zone for a good drop rate on the eggs. Better drop rate on the max luck suits but those get real expensive to put together. LOL I was doing Origin with just my miner mule toons with 2000-2200 luck suits and killing with 2 untrained fire beetles and a untrained blue beetle Best hour was 59 eggs across 3 characters worst hour was 45 so the RNG rolls come into play as well. Ran some 1000-1200 luck suits (Best I had on Cats) and was doing 10-16 eggs per hour across 3 toons........ May as well have thrown those thorns in the trash barrel.
