The new changes to the game made every game so 1 sided

Starting from minute 7 on wards games starting to feel more 1 sided. 1 mistake in a lane or jungle get punished with a loss of lane or game right away. Games end so fast almost down between 15-25 minutes. I literally started to lose hope about myself. I peaked diamond last season and ended the season Plat 1 and with these new changes I have an insane losing streak and I usually have a consistent match history. Now it more like I have a consistent losing streak. I know some haters going to comment on this saying its just me I suck. But like my point is gamess dont feel that competitive and the moment you pass 7 minute mark you kinda get the idea which team is going to win. Hoping riot can do some changes and make games feel more competitive and more equal for both sides. Thank you for reading this. Hopefully this will give some ideas about whats going on in summoners rift
