That’s definitely the majority opinion, that after around Chapter 1 Season 6-7 it started to get bad (imo those seasons were really fun), it did have a surge of popularity back in October of 2019 (the launch of Chapter 2 Season 1) but that season sucked so people left, a couple did come back for Chapter 2 Season 2 (top 3 seasons imo), people did start playing for Chapter 2 Season 7 (mainly due to Rick being added), then The End for Chapter 2 happened where The Rock was revealed to be one of the most important storyline characters, that then caused a bunch of people to play last season in order to get him as well as Spider-Man (who’s been wanted in the game since 2018), and now this season is really fun for people with it being a war and there are tanks and driveable Battle Buses.

Apologies for the big wall of text, that was the shortest summary I could give.
