I was just offered to buy x10 Frags for Thylessia. I have 55 frags on her, but pulled her early. She is good, but I wouldn't buy the extra frags at $10 for x10 frags for an Epic, espeically one I already have. Now what I *would* buy and have in the past is Frags for a Lego even one that I already have. During the Ruel fragment I pulled him early. I ended up with 75 frags, then I got 15 more for this past frags for prior fuions. Thank you for that, but that still only got me to 90 frags. I would *LOVE* to buy those last 10 for a dupe Ruel. $10 for a dupe Lego is fine by me. Why not offer me Ruel frags instead of for an epic?
Every once in a while there is a catch-up event for Fragments- the first one was during Raid's Birthday 2021 and the second was just maybe two weeks ago.
The fragments will definitely come back eventually. You just may have to wait a while.
Will see, how they add this feature for better characters too.
