Your top examples of good and bad luck in this game
First bad - I started this game one week before the 12.0 update and rolled a four star dr strange. The account went from incredibly blessed to frustrating within one week
Second bad - I became uncollected on Christmas Day - an hour after special prizes were sent out (five star awakening) to those who were uncollected. If I had known I would have grinded the day before.
First good - after becoming cavalier I bought six cavalier crystals and rolled 5 five star (including blade, ca iw, and omega red) and a six star (mephisto)
Second good - yesterday I grinded the last if the 15k five star shards for the featured five star crystal and rolled guillotine 2099. I was happy because the first 3 featured I had bought were dupes. But, I actually wanted dr doom. Then, that evening I opened a grandmaster crystal after getting my 100 grandmaster shards and ended up with... a five star dr doom
