Step 1 - Skip a traditional seasonal event that usually gives the fans a welfare Servant and decent to amazing card art.
Step 2 - Replace said event with one that has no welfare, a shoddily designed SR (I'm sorry but Jane looks like a 3-Star designed by the guy who did Boudica's outfit), an SSR that's basically just another Rin-face but kuudere instead of tsundere, and a story written by the franchise's founder that tries to make all the previous comedy events canon.
Step 3 - Skip a rerun of another traditional seasonal event that gave the fans one of the best welfare Servants in the game, in a class that until now has only been populated by SSRs.
Step 4 - Have the new seasonal event give us a welfare version of a popular character to gain their trust back...
Step 5 - Then introduce a welfare version of a completely different popular character in the arcade version of the game that most of the fanbase doesn't have easy access to.
