I have no idea why you got rid of the "logout" button but it's really important, honestly removing it is one of the reasons I took time off from Paladins! Allow me to explain.
Whether due to my sometimes slow connection, or the game's shenanigans, bugs happen, and, when they do, a quick logout would in most cases refresh the game getting rid of the bugs, but now, I CAN'T logout, and I'm forced to restart the whole game, which on my old laptop is like 7 whole minutes, not to mention, sometimes the bug resides, and I have to restart the game, yet again! it's been a huge pain and a reason for me to hesitate to start up paladins and play.
In short, TL;DR, PLEASE bring back the logout button it did nothing wrong ;-;
Edit: Example of a VERY COMMON situation:
Despite having a pretty decent (81 ping average) connection, after a match it's a 50/50 chance of losing connection, showing me a bugged stats screen as if I'd lost connection, when i leave to main menu, it just shows the "Reconnect" button, after like a minute or two of clicking it or waiting, it eventually logs me into my account, BUT, yet again, it is as if i've lost connection, I cannot change any settings, I cannot collect daily reward, can't chat or invite, and can't queue (shows no gamemodes 0/0).
and if I do restart the game, it is then a 25% chance of having that same problem happen
