Auto leaver even with return

when i randomly disconnect but take 5 mins to jump back in it gives me LEAVER even when i jump back in AFTER THE START OF THE GAME to win or lose even 10 mins after and LONGER after reconnect. like whats the point of reconnecting if you just get leaver in the end, its like saying fuck you even if you jump back in to continue. the new system is fucked and u auto get leaver no matter what. p.s. using slow pc so it takes time to reconnect. it sucks already
