Removing AFK warnings in custom/sandbox games

Can riot do some thing about about AFK warnings in custom/sandbox games they r so annoying?Sometimes i am waiting for my rod of ages to stack or maybe wait for baron to spawn.But when i come back i see the game is over because of these AFK warnings in games where i am literally the only player . It makes no sense for it to exist ,and i hope it gets fixed soon .

PS:i was playing ryze in a sandbox game and realised the mana cost is missing on his Q (missing on the icon not description).So fix that aswell
