I have traced all league's problems down to 1 source.

It is the competitive scene aka LCS that ruined league. Right now riot wants people to watch their competitive games rather than to actually play the fucking game. Which is why they want to make games as snowbally and as short as possible so the LCS can be "exciting to watch. If I wanted to watch an exciting match, I would just watch some bronze v replay. Even my silver games have insane objective gains off of just 1 early teamfight. Baron dies in single digit time when it spawns at 20 min so you can't contest if you have 2 bot or even just 1 because baron doesn't do much damage. Midgame doesn't exist anymore. Once bot lane starts rotating, you have to play the game like it's a full item lategame because one mistake from one teammate spirals the game out of control. Yet, still lots of worlds games lasted a long time, so I can guess that riot will try to make league even shorter. Which it looks like they are actually doing by introducing a turret breaker rune and increasing damage creep. We already see even in bronze the average game length is less than 30 minutes. It will get to the point where the average game length will be so low that I could play a league game in between classes for fucks sake. Riot games, this is not call of duty or counter strike. The game needs to last at least 40 minutes to experience the full game with all stages. End of rant
