That's partly because it's now more important to know what you're doing, than figuring out what you're doing, or just enjoying the fight. Unless you're willing to just tank insults while playing, and rebuild and retry with constant leavers, you have to study. Usually people try, but often they sit back and give in to "experiencing" games through video instead.
WoW for example has almost no tolerance for flawed teammates anywhere anymore, I've seen countless groups that would rather sit outside a dungeon for hours, than be inside it for 15 minutes too long.
And people no longer think "if you want good teammates, you have to build a team", they instead think that everyone who joins the random matchmaker has a responsibility to be good. It's rude to be bad at World of Warcraft.
