Are we all so entitled that we can't just come back in a few hours?
They're going to fix this by the end of the day, a feat that we will all take for granted. Let's just chill and do something else while the (underappreciated) programmers work double-time to stabilize things. Programming is difficult and bugs always pop up. Let's be kind and not lie to ourselves that League is exceptionally glitchy when it's really not.
The Epic Games client erased my save data for Borderlands 3; Heroes of the Storm takes five times longer to update and doesn't display a progress bar for in-game updates. Yes, it's annoying that League crashed, but bugs happen.
See you all again in a few hours! GGs!
