I'm not underestimating the low drop rate but how could you explain the amount of crystas going on sale here? Since I came back 2/3 months ago, I've been monitoring the Selling section of the forum. Sold all my prenerf and decided to collect crystas. I've managed to get started on the R9 crystas and other reqs with different dmg mod. I am currently at 10 crystas and there are still a few auction that i have a bid on.
basically what im trying to say is that it may be a good thing for me and other collectors. I can farm it myself or acquire it cheaper. I don't mind about the value of it dropping. I just wanted to have my own collection. This farm vid is good! Am I going to farm my own? Possibly. But I am currently working on a separate project in game. I don't mean to be negative.
What you’re implying is that this solo farm from the video would make Crysta’s “cheaper and less rare.”
I’m not entirely sure what you mean by “cheaper” or “less rare,” but the way I read it is that you expect this farming method to (significantly) tank the prices. And on that point, I would disagree, simply because the drop rate is so incredibly low.
Let’s say, hypothetically, that 20–50 people started doing this solo farm (which I already think is a ridiculous number) and each of them ran the instance 5 times per day (around 2.5 hours of farming). Even with that many people farming, on average it would still take somewhere between 3 days and a week for a single Crystalline to drop. Then you need to be lucky that its a gold one, because it also drops purple on average way more.
That’s exactly why we haven’t seen many gold valuable 15^50, +5, DV, or DZ Crystallines over the past three months. The drop rate is insanely low, so even if a few people started farming this way, I don’t think it would have any meaningful impact on the rarity or prices of Crysta’s the way i think you are assuming.
Don't get me wrong, every dropped crystalline would have a impact on the market, i don't think this farm (the one you are reacting to) will have any meaningful impact.
