There are a lot of reasons behind, like people playing much less Candy Crush Saga these days, pages in this wiki are very detailed at the moment (hence getting fewer edits to further improve), having bots may minimize a lot of man-made edits etc.

Yes the wiki may be declining, but saying it's dying is over-generalization imo.
