I just recently logged in to the sfwfkg version get some puzzle gold and got Queen of the Night as my 5 star welcome back. That's a better return from not playing the game for [months] than I got from throwing [months] worth of gems into the gacha prior to quitting. Seems there's a pretty clear logical choice to be made here.

And there's the irony: you were given a 5* for playing again, when having better luck with pulling a 5* might have prevented you from leaving in the first place.
