@Riot Why is it okay that your client makes me lose my series?

According to my duo partner, we are indeed in champ select, but Riot's shitty client decided to try to load something from the home screen that I accidentally clicked on after the client FORCED itself to teh forefront of my screen. It's not okay for it to run processes during champ select. It's not okay for the client to move to the front of every page I have open, and to top it all off, the client is a huge fucking resource whore. The biggest esports company in the world with the most popular game in the world has no resources to fix a BASIC element of infrastructure. But "It's okay when Riot does it."
