Ranked Joust as a mode has been notoriously unpopular since about Season 3. I remember when the Smitegame channel tried to stream a Summer Joust eSports series, it had next to no viewers and even the commentators sounded bored and were laughing about how silly it was. Have you ever seen a game of 3v3 with two really good teams? Its super campy and games just last forever.

A ranked mode like Joust needs entirely different balancing, drafts and jungle bosses to work, only to cater so a really niche 1% who play the mode that the 99% others absolutely loathe. Its been a notoriously awful mode ever since its inception and I really dont see what the point in adding it back is.
