I've never had such bad time with the game as I do now

This preseason is a complete fuckfest, doesnt matter if you outplay your opponent or do well in lane. There is no strategy to anything, just 2 teams collapsing on one another and whoever does more damage in 1 second wins. Assasins are unstoppable, dark harvest and electrocute are just fucking retarded. I feel like the game is completely outside of my control, just which team has picks that can make better use of the insane damage the runes provide. In 2 days I lost about 200 mmr, whenever I play ranked it just feels like an aram. Tanks mean nothing, one of the games i played we had a huge lead, 5 towers in 15 min, enemy adc didnt even exist in the game. But we still couldnt win a teamfight against 3 fucking assasins depsite having trundle and nasus on the team and being ahead in gold. Runes are fun to manage in the inventory but the complete opposite in game.

On top of that, there is less incentive to play games at all with the new ip leveling. If it wasn't for ranked I'd probably just leave the game completely until its fixed. I know it's just a preseason and things are supposed to get better but it doesnt change the fact the game is horrendous at the moment and just not fun to spend time with. I never expected I would say this but right now I miss ardent and tank meta, at least there was any sort of strategy to it, it required more cooperation, objective play and rotations.
