People saying Dunkey Made good points
First off the complaints that dunkey made in his video hold all but are not limited to EVERY FUCKING MOBA. Dunkey doesn't have a problem with league he has a problem with the moba genre. People afking, feeeding, being toxic, not being fun after certain ammounts of time is in all mobas. When you have a genre last from 20 minutes to hour long games were you can't solo carry like COD and actually have to work as a team you run into these problems.
Now i'm not defending riot in champion design and balance in some cases but i think they've done a better job than most mobas which is why it's still numero uno. You can take dota 2 approach make every ridiculous op and don't have items scale with abilities and abilities are just naturally strong as you level up. But then you run into the problem of certain heroes literally just being flat out weaker than others with or without items.
Or you can follow smite were everything is for the most part balanced if you have waveclear and aoe your super slow, if you have mobility and high damage you have no aoe waveclear or high survivablity. But then you run into the problem of the game getting so dull because theres no stupid op fun champion like in league or dota.
You can't expect to review league in 2 to 3 minutes and not give out specific points. He based everything on the moba genre and not league as a whole. While i do admit league is far from perfect and never will ever get close but as a game in the moba genre i feel is doing pretty good. (Even thought just yesterday i thought about quitting xD)
