Lol so true, this last patch had way too many changes that clearly were no anticipated or thought about. The state of the game is unplayable to me and I've been playing for years. Lol games are decided sub 10 minutes and over just over 20. Turret fall like paper and 75% of champions (mid to late game champs) are utterly useless because of such fast game times. Losing teams have almost no chance of comebacks due to how hard winning teams snowball. Couple ideas to help get the game back in working order.
Revert patch 8.11 scrap it
Lower first turret gold
buff turrets pre 10 minutes
Get rid of herald ability to 1 shot turrets and further snowballs (make it worth 300g or something) or honestly remove the thing all together. It allows for way too much snowball potential for winning teams, let the winning team win through better map rotations. I never liked the herald idea tbh.
Just a couple ideas but currently the way the game is now like you said it's completely a blaze.
