It's not worth, i have a friend that started playing lol, and when we play he gets so angry, i stopped from playing it because everyone is toxic, and when u are playing a match for more than 20 minutes, you start to have a lot of pressure and if you or your teammates fail doing something, u will get flamed or you will flame, so you get angry and toxic too.
The start of league is probably the hardest for the simple fact that there is so much toxic players. However, once you've reached level 30 I would highly suggest going into rank and playing even if you're new but play champs you're able to carry with because at times it'll be the case of you leading your team to a win. I rather play ranked than normals because in rank you're playing with people trying to win and people based on your skill and not people afking or inting because they're tilted. However, if you want to try a new champ I suggest doing it in normals since your team will tilt.
Once you hit level 30 you'll realize that you actually developed a crippling addiction to the game even though you've started to hate it by this point. Three years later and 2 new accounts down the line and you start to question yourself why you still play the game, considering you're still hard-stuck Gold.
