Can We Please Be Able To Log Out Of Client Without Having To Close It?

Why cant we log out of 1 account and log into another without having to close and reopen the client?

I never knew you could not do this because I've always just had 1 account. I decided to make a new account just to see what the new player experience is right now. ( So far not good lol.......i seen 1 person get threatened to be reported for going bot to support the ADC. The ADC raged them and said "fool im ADC gtfo) lol i guess they thought ADC meant sa solo role? But thats off topic right now.

So i go to change accounts and thats when i see you cant just log out and login to a different one. Why? The game has been around so long why hasnt this been implemented?
