Why LOL is bad

i mean, I like the game, i grew up around rpg style games of leveling up and buying items for stats and stuff with strategy, league is that but with real people, it makes me really test my strategies, you gotta play some ranked or watch youtubers explain how to get good to really understand the beauty of the game. The only problem i have with league is that its so time consuming, like I cant go to school, work, and play enough league around it to actually improve a ton lol.
