I agree with this. Early Blizzard games had amazing worldbuilding and great single player experiences, with good multiplayer options.
After WoW's success they seemed to try to pigeonhole all of their properties in the same direction, SC2 and D3 were quite clearly online/multiplayer first with single player as an afterthought, and the world depth felt lacking. Hearthstone's alright but feels like it has too much focus on PvP games and loot box mechanics.
Hearthstone's aesthetic reminds me of the parallel world of stuff that religious groups always make (Christian music, Christian books, etc), and I found it really offputting.
