Can't remake a 4v5 game (IN PROMO)

So basically, i was in promo for plat 4 right now (still am with 2 losses), but that wouldn't be unusual and interesting about except given the fact that i lost the second game bcs we were playing 4v5 since the start (a player disconnected at 0:01), and we were unable to remake the game. And i lost a game in promo for your mistake. the most important part is that you can rework all the champions that do not need a rework, you can add new features like TFT that is coming soon, but you can not fix those stupid things that are the cancer of this game, that are driving people away, that makes you take your PC, Laptop, whatever you are using, and throw it out. It's a tilter, a huge one. Who would want to play a game after this? How am i supposed to go and play another game of ranked when i have in my head, that is gonna happen again, and gonna lose promos because of a troll, or because someone goes afk. You had a loss prevention system that just did not count that defeat.
