Both of those were fine in the beginning. HS became impossible to play without endless grinding or spending money. Overwatch became tedious and toxic, due to both the players and how the developers responded (spamming in-game voicelines is now "toxic").

I think people just got fed up with online trading card games and the grind/monetization that they have. At least with MTG I can resell the cards... In fact MTG online with cockatrice is way more fun than HS or any of the other clones.
