He is just hoarding moonstone covers to take advantage of the buy back program .. But d3 squashed it as there is no hp involved by sellling moonstone covers..
Yeah dozens of Moonstones is the result of speculating. People knew her powers were getting changed and typically when that happens you can sell changed characters for HP (supposedly that isn’t happening with Moonstone and you’ll only get ISO).
Some people will keep several copies of 1/2* Widow to send out as team-ups. I imagine somewhere there’s a guy with several copies of Juggernaut so he can play the rare Balance of Power/Combined Arms event even more efficiently.
That person is definitely prepping to sell of moonstones (but there is no HP buyback price this time, so that may be a nasty surprise this time)
One other reason to stockpile low level characters is that you will automatically recruit any character that you open in a token and don’t already have fostered. That can be a pain if you would prefer to wait before decide what to do with a particular cover/slot. So using 1* and 2* covers to hold otherwise fallow roster slots can be useful here and there.
I made a second Moonie two weeks ago in hopes of making a small profit. Since then I’ve gotten 4…4 covers of a 2* in 2 weeks. It’s crazy. And I still haven’t max covered MNMags back from when I sold him. I’m not a conspiracy nut, but that might change soon.
