New client bug?

No "reconnect" button when you DC from a game. The actual game itself would not load on my screen but i could hear the game going on. In panic, i had to force close the game only to find out there's not a reconnect button like in the old client. So i had to close it and downgrade to the legacy client in order to do so. I was successful with connecting to the game before the AFK time out, but i was 5 levels behind the enemy team. Do they care? of course not, so i get 3v2d and 4v2d all game until theres no point of come back for me. Really ruined the game and i'm actually quite mad. You might say "well why didnt you just play well enough to not be behind so long?", and its because im human. I know this thread probably won't bring any changes but i just want to share my experience. I'm aware the client is in Beta but this is an unacceptable bug. What if i didn't make it in time to avoid remake, and now i get to deal with a leaverbuster queue timer for 20 minutes? I know there is a slim chance this even gets acknowledged but the new client is complete garbo and riot should reconsider making it available until it is at least decent.
