1. I don't have millions of money on my account. I have barely over 400k right now, so anything of value is good for me.
2. The chests are a nice addition to my house
3. Lockpicking is a thing I am developing on my T-Hunter, not for the money but for FUN. I know, that compared to plain spawncamping, T-Hunts don't pay off.
4. I can't kill all the stuff in the event and the wisps are the only things (besides the trashmobs of course) that I can solo fast and without risk. My mare shreds them to pieces in a matter of seconds.
5. On top of the chests and threads from the wisps, I collect chests lying around and any good item from the corpses and from left behind corpses I can find. They are good enough items for my other chars, since they are just developing and some may even have resale value.
The best +luck items I was able to find were two +75 jewels, so not that good, but I found some nice looking armor with 50+ resists.
So to answer your post, rwek, if you have mainly doom-quivalent equipped characters on your account(s)? than I see the validity of your post.
For someone like me, the event is much more than just "farming" the artifacts
And besides the collecting part, it actually is quite fun
And you should see my house right now. LOL It's littered with dozens of chests
Since I was killing wisps all night, I didn't have the time to go to get the last LP points. So I am storing the chests in my house. If the event goes on for a few more days, I will have to rent a depot
